Bug Description
Deleted files on NFS are not being handled properly. This was demonstrated with the evince profile, but could happen with any confined process. This is a regression over jaunty and earlier.
Previous description:
All PDFs I try and load with evince end with evince showing me a wonderful grey screen with no content, and the window controls as usual (Max/min/close). PDFs open just fine with xpdf. This was working until about a week ago....
Upon launching from terminal, I get this:
** (evince:7414): WARNING **: Failed to create dbus proxy for org.gnome.
** (evince:7414): WARNING **: Failed to create file '/home/
I don't know if these two warnings are related to the app failure.
I tried removing .gnome2/ and that didn't help either.
Version is GNOME Document Viewer 2.27.90 / 2.27.90-0ubuntu5 in Karmic.
Running it through strace seems to end up in an infinite loop of these:
poll([{fd=4, events=POLLIN}, {fd=6, events=POLLIN}, {fd=7, events=POLLIN}, {fd=8, events=POLLIN}, {fd=9, events=POLLIN}, {fd=12, events=
read(6, 0x98be900, 4096) = -1 EAGAIN (Resource temporarily unavailable)

Thank you for using Ubuntu and taking the time to report a bug. Can you attach your /var/log/kern.log right after you try to open a PDF? It is possible that the new apparmor profile is causing you trouble.
