backintime-kde crashes (kde4systrayicon.py)

Please open a terminal and run 'crontab -l'. Copy & paste the command (starting with 'nice -n 19 ...') and execute it. Then post the output in here.

$ crontab -l
#Back In Time system entry, this will be edited by the gui:
*/30 * * * * /usr/bin/nice -n 19 /usr/bin/ionice -c2 -n7 /usr/bin/backintime --backup-job >/dev/null 2>&1

BTW: I should have mentioned that this cron job was created by backintime-gnome. I have recently switched to KDE, and the error message popup has right then.

That command is the same with gnome and kde GUI.
Please run '/usr/bin/nice -n 19 /usr/bin/ionice -c2 -n7 /usr/bin/backintime --backup-job' in Terminal and post the output.

$ /usr/bin/nice -n 19 /usr/bin/ionice -c2 -n7 /usr/bin/backintime --backup-job

If that returned no errors, it must be related to missing environ variables.
Can you please run the command again with leading 'env -i PATH=<path> USER=<user> LANG=<lang> <command>'
Where <path>, <user> and <lang> is the output of 'echo $PATH', 'echo $USER' and 'echo $LANG'.

... and HOME. If I do:

env -i PATH=... USER=maeder LANG=... HOME=... /usr/bin/nice -n 19 ...

the error does pop up. The output contains:

WARNING: import keyring failed
backintime(5806)/kdeui (kdelibs): Session bus not found
To circumvent this problem try the following command (with Linux and bash)
export $(dbus-launch)
KCrash: Application 'kde4systrayicon.py' crashing...

after which the rsync is done successfully.

If I add DBUS_SESSION_BUS_ADDRESS, DBUS_SESSION_BUS_PID and DBUS_SESSION_BUS_WINDOWID to the mix (according to the output of echo $(dbus-launch)), everything runs smoothly:

env -i PATH=... USER=maeder LANG=... HOME=... DBUS_SESSION_BUS_ADDRESS=... DBUS_SESSION_BUS_PID=... DBUS_SESSION_BUS_WINDOWID=... /usr/bin/nice -n 19 /usr/bin/ionice -c2 -n7 /usr/bin/backintime --backup-job

etc.

Please apply attached patch with 'sudo patch /usr/share/backintime/common/tools.py < dbus.patch'. Than run 'backintime --pw-cache stop; backintime --pw-cache start' and try again.

The attachment "dbus.patch" seems to be a patch. If it isn't, please remove the "patch" flag from the attachment, remove the "patch" tag, and if you are a member of the ~ubuntu-reviewers, unsubscribe the team.

Sorry for not responding earlier, but the bug hadn't occurred since a reboot at the weekend. I still applied the patch some days ago.

Unfortunately, the error popup has just started to appear again some minutes ago.

The difference to earlier is that I haven't done a reboot, but switched from one user's KDE session to another's. Could this pose a problem?

Sure. If you switch users you'll have a new dbus session. But BIT has still the old session in cache. So it will fail. Not sure yet how to handle this. I'll think about it. Did you switch users last time, too?

I don't remember whether I switched users, but I may well have.

This bug was fixed in the package backintime - 1.0.36-1

Thanks.

I now have the following versions:

ii backintime-common 1.0.40
ii backintime-gnome 1.0.40
ii backintime-kde 1.0.40
ii backintime-kde4 1.0.40
ii backintime-notify 1.0.40

I have just switched KDE user for testing. I am not able to start backintime-kde4 currently (see below).

I haven't determined yet whether it's switching users that causes the problem.

backintime-gnome starts and works.

$ backintime-kde4

Please report this in a new bug report filled against https://launchpad.net/backintime (not the Ubuntu package). This has nothing to do with this bug.

This happens because you have installed both backintime-kde4 and backintime-gnome. As soon as you remove backintime-gnome the kde4 app will work again. But for sure I consider this as a bug.

> As soon as you remove backintime-gnome the kde4 app will work again.

Confirmed.
