Launching totem when frei0r-plugins is installed shows: Could not load classifier cascade

Just to add that this happens for brasero and for totem too with the same error message (but without (empathy:3052) -warning).

is the file there? /usr/share/opencv/haarcascades/haarcascade_frontalface_alt2.xml ?

cat /usr/share/opencv/haarcascades/haarcascade_frontalface_alt2.xml
cat: /usr/share/opencv/haarcascades/haarcascade_frontalface_alt2.xml: Tiedostoa tai hakemistoa ei ole

(Tiedostoa tai hakemistoa ei ole = file or directory is missing)

cd /usr/share/opencv/
bash: cd: /usr/share/opencv/: Tiedostoa tai hakemistoa ei ole

-->No, the whole opencv folder is missing. I'm getting this bug after I made a clean install of Karmic RC.

Should I open this bug for ubuntu-desktop (or -meta) or to ubiquity?

re assigning to opencv.

seems to appear when installing frei0r-plugins (example: for kdenlive). When removing frei0r-plugins from my karmic I've no error messages at all, and totem (and other apps) runs fine.

Why is the missing file only provided in the following packages:

sudo apt-file search haarcascade_frontalface_alt2.xml
gnome-mousetrap: /usr/share/pyshared/mouseTrap/haarcascade/haarcascade_frontalface_alt2.xml
harpia: /usr/share/harpia/images/haarcascade_frontalface_alt2.xml
libcv-dev: /usr/share/opencv/haarcascades/haarcascade_frontalface_alt2.xml
sivp: /usr/lib/sivp-0.5.0/etc/haarcascade_frontalface_alt2.xml

I don't want install libcv-dev (100MB with dependencies) to get some Gnome apps working.

Thomas: I can't yet test your suggestion because I need lives for a while.

Developers: Please fix the conflict between frei0r-plugins and opncv packages.

Confirm: removing frei0r-plugins package dress this issue...

Hth

Workaround confirmed here too.

Confirming the problem and the solution.
Just installing kdenlive makes that frei0r gets installed and in turn makes that totem can't start.
Uninstalling frei0r fixes the problem.

installing LiVES install frei0r too, but ca'nt be installed without frei0r (removing frei0r automatically remove LiVES).
We can use totem and kdenlive if we don't install frei0r but we must choose between totem (and so other gnome apps) or LiVES.

I confirm this bug with the frei0r-plugins package using lives in Ubuntu Karmic

This isn't a bug in openshot, but in opencv and/or in frei0r.

I am running karmic and am also experiencing this bug - uninstalling frei0r-plugins resolves it. I then built frei0r-plugins from git and installed it using checkinstall. Now, after running rhythmbox I receive the following error:
$ rhythmbox
(rhythmbox:18793): GLib-GObject-CRITICAL **: g_param_spec_internal: assertion `(name[0] >= 'A' && name[0] <= 'Z') || (name[0] >= 'a' && name[0] <= 'z')' failed

ERROR: Caught a segmentation fault while loading plugin file:
/usr/lib/gstreamer-0.10/libgstfrei0r.so

Please either:
- remove it and restart.
- run with --gst-disable-segtrap and debug.
Error re-scanning registry , child terminated by signal
Run 'rhythmbox --help' to see a full list of available command line options.

It seems that the offending file is /usr/lib/gstreamer-0.10/libgstfrei0r.so . Is it possible to replace this object file with an older version? Is it necessary for openshot to function?

Garibaldi: Test and report. The file "/usr/lib/gstreamer-0.10/libgstfrei0r.so" might not cause this bug since it´s not shown in the original error message.

I upgraded from the custom built frei0r-plugins to the official one in the repository and rhythmbox still starts okay! I checked the package from the repository and you were right - libgstfrei0r.so does not exist in the official build.

It seems to be a problem with a librairie of freiOr-plugins (/usr/lib/gstreamer-0.10/libgstfrei0r.so) and Gstreamer. So it's not a problem of Openshot.
Good luck

Looks like the same issue on Xubuntu 9.10 and OpenShot:
https://bugs.launchpad.net/openshot/+bug/511099

Bug#470564 seems to be a duplicate of this one.

Interesting, at https://bugs.launchpad.net/ubuntu/+source/software-center/+bug/470564/comments/3 Stinger says that removing gstreamer0.10-plugins-bad solves this problem.

There has been some discussion of this bug at:
http://ubuntuforums.org/showthread.php?p=8377817
http://ubuntuforums.org/showthread.php?t=1343696

I had the same problem especially with these apps:

- totem
- gnome-app-install

both of them tried to start, but crashed;
this has solved my problem:

<b><u>sudo apt-get remove frei0r-plugins</u></b>

like in this link:
http://ubuntuforums.org/showthread.php?p=8377817

Both applications work now.

Have had no issues with frei0r-plugins and openshot (latest from experimental) on karmic
Am using gstreamer packages from here instead of the karmic ones

https://launchpad.net/~gstreamer-developers/+archive/ppa

Closing this part of plugin since there's no error message or problems to start a gnome application if this package is installed.

Lucid update: You *can* use gnome application while frei0r-plugins (which installs some opencv packages) is intalled. I tested this with totem, brasero, rhytmbox and software-center in fully updated Lucid Beta1.

Bad news: If frei0r-plugins is installed, launching totem will show the error message but totem will open normally. Uninstalling frei0r-plugins, but leaving the libcv packages will not the show the error message on totem startup.

Reopening as a consequence of comment 26.

the issue is not a totem one

As i wrote in bug#470564

"I got the same bug and can confirm that removing the frei0r-plugins solves this issue.

But removing gstreamer0.10-plugins-bad solves it too, as described in bug#471690 , without having to remove the frei0r-plugins ( Openshot depends on it ).

So it seems that these two plugin packages ( frei0r-plugins and gstreamer0.10-plugins-bad ) can not co-exist without causing trouble."

It must be either frei0r-plugins or gstreamer0.10-plugins-bad who is causing this bug.

kdeinit4: preparing to launch /usr/bin/amsn

aMSN would launch, but trying to login to the network made the application crash. No other notification other than that line in .xession-errors (took me a while to figure out to check in there).

sudo apt-get remove frei0r-plugins

resolved the issue

lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 9.10
Release: 9.10
Codename: karmic

@Photodeus: This bug is worse in Karmic than in Lucid (please read comment 26 for more information).

@subscribers: It might be a good idea to test totem's launching from terminal with up to date Lucid since GNOME was updated between Lucid's dev releases and Lucid final.

I think the problem is that opencv pacakges do not install the haarcascades, this also impacts Digikam 2.0.0 beta 1 see here:
https://bugs.kde.org/show_bug.cgi?id=262074

i hope this bug can be solved soon, there is a new upstream release of frei0r since October 2010 (version 1.2.1) which solves other issues on other distributions, while the recent commit 55ed8391 in our code might solve this one.

i'm planning to:
 - test this bug and make sure it is solved upstream before our next 1.3 release.
 - once done upload a new version on my ppa.

ciao

jaromil, upstream maintainer of frei0r-plugins

upstream frei0r 1.3 release now fixes this bug.

i'm now uploading a new .deb package on ppa:jaromil/frei0r

This bug is fixed in upstream, but not yet in Ubuntu as Natty has v.1.1.22git20091109-1.1 of frei0r-plugins.

Closing this part of the bug report as this bug is being fixed in frei0r.

The v.1.3 seems to be a unstable development release -at least it isn't mentioned at http://freshmeat.net/projects/frei0r/releases

frei0r 1.3 it is a stable development release.

i'm just done compiling and uploading other packages, cross-compiling for different platforms and then also updating the webpage on freshmeat. it all just takes some time.. will be up on freshmeat within 24h.
thanks for reacting so fast!

packages ready on ppa:jaromil/frei0r

Is the package in your PPA ready for Ubuntu's official repositories or does it need modifications before it can be copied to there?

The v.1.3 is both in the ftp and Freshmeat site.

i suggest for the future to take the source repository and the GPG signed message by upstream maintainers as authoritative source for a new release. thanks for your attention to details!

jaromil: can you make the packages available for maverick?

it's on ppa:jaromil/frei0r

if problems arise and you can fix them youself i'm happy to incorporate contributed patches upstream (either in master or ubuntu0 branch) just please format them with 'git format-patch'

ciao

i'm sorry but the ppa is not accepting it. i don't know what's wrong: ultimately its just a matter of changing a debian/changelog name, yet it seems there is more to do and i can't do it alone.
i guess there is someone that has more experience with launchpad here? below the error i get:

Rejected:
File frei0r_1.3.orig.tar.gz already exists in frei0r, but uploaded version has different contents. See m
ore information about this error in https://help.launchpad.net/Packaging/UploadErrors.
Files specified in DSC are broken or missing, skipping package unpack verification.

BTW the ubuntu0 branch is in our GIT upstream
 http://code.dyne.org/index.cgi?url=frei0r/tree/&h=ubuntu0
i guess already imported in your bzr, should be easy to add a target for build, no?
how?

Thank you for reporting this bug. Please report this to Debian. Once Debian packages the new release which presumably has this issue fixed, then it is very easy to sync Debian's newer package to Ubuntu.

Never mind my last message. It looks like this was reported to Debian a year ago.

We really need to fix this in Debian & Ubuntu, not just in a PPA. As of yesterday, gnome-video-effects used by cheese depends on this package.

Marking as medium for now since cheese, gnome-video-effects, and frei0r-plugins are not installed by default in Ubuntu 11.10.

what does this means?

why de-assign it?

I've fixed the bug already since long time.

I don't understand what is the workflow, who has the power to upload
and how that can be transferred. providing the fixed package on my PPA
is all what i can do. please if you have time and patience explain me
how this works. i would like to have this fixed, but there seems to be
some beaurocracy i still can't figure out.

thanks

The general workflow is documented at https://wiki.ubuntu.com/Bugs/HowToFix

Specifically, to get a brand new version into the current development release (Oneiric) you would do something like:

bzr init-repo frei0r
cd frei0r
bzr branch ubuntu:frei0r oneiric
cd oneiric

Make sure the watch file is up-to-date (in this case, add the appropriate watchfile)
If you had to make changes, then you'll need to bzr commit

bzr merge-upstream
Make any additional changes to the debian/ directory
dch -e to edit the changelog (& update the timestamp automatically)
I then usually do bzr uncommit to undo the commit necessary to run the bzr merge-upstream command

bzr commit

bzr push lp:~jaromil/ubuntu/frei0r/oneiric/frei0r-1.3.1 (the last part can be named whatever)

Then visit https://code.launchpad.net/~jaromil/ in your web browser
Click the propose merge button and submit the merge proposal.

Then find someone with commit access to review your submission.

If you have any questions, feel free to ask in #ubuntu-motu

Hi there. Guys, I'm not sure what is wrong in your process, but this bug was fixed by an upload of release 1.3 already YEARS ago.

Frei0r 1.3 It was never incorporated in Ubuntu despite this bug being open here.

Meanwhile after years we released version 1.4 and it is a rather useful package for your users, see for instance https://www.youtube.com/watch?v=xcFFo_bqg_4

I'm wondering today, how everyone must be struggling with getting it installed and what's wrong between us.

As upstream, I've tried my best, even learning your system and pushing stuff being compiled in your PPA.

Now I'm just sayin', this bug is rather depressing.

ciao

BTW, FWIW this ppa has 1.4 ppa:sunab/kdenlive-release

I opened bug 1186039 to track the progress to update frei0r in Ubuntu's repositories.

This bug was fixed in the package frei0r - 1.4-2

---------------
frei0r (1.4-2) unstable; urgency=medium

  * Suggests: opencv-data (Closes: #587736, LP: #459940)
  * Upload to unstable (LP: #1186039)

This Bug affects me, when i installed kdenlive under Trusty Tahr (Kubuntu 14.04 LTS);
Dragon Player is alwas crashing, running vlc minimized the crashes, but kdenlive isn't usable.

When i startet kdenlive in a terminal, i got the above errormessage:

ERROR: Could not load classifier cascade /usr/share/opencv/haarcascades/haarcascade_frontalface_alt2.xml

a locate says, that this location doesn't exist, instead this file is located elsewhere:

I also see this in 14.04 with kdenlive. It's not fixed.

Upstream developer here, who managed the release of this fix back in summer 2013.
It is ridiculous how Debian and Ubuntu are ignoring our software.
I can only recommend to change distribution.
