Reducing to Medium for now as I am not sure if High is appropriate.
Please adjust as necessary.

** Summary changed:

- evince fails to open all PDF - grey screen
+ apparmor not properly handling file deletion on NFS

** Description changed:

- 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....
+ Deleted files on NFS are not being handled properly. This was
+ demonstrated with the evince profile, but could happen with any confined
+ process.

  Upon launching from terminal, I get this:
  ** (evince:7414): WARNING **: Failed to create dbus proxy for 
org.gnome.SettingsDaemon: Could not get owner of name 
'org.gnome.SettingsDaemon': no such name
  
  ** (evince:7414): WARNING **: Failed to create file
  '/home/twigathy/.gnome2/evince/evince-crashed.HMQ0YU': No such file or
  directory
  
  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=POLLIN|POLLPRI}, 
{fd=14, events=POLLIN|POLLPRI}, {fd=15, events=POLLIN|POLLPRI}, {fd=3, 
events=POLLIN}], 9, 0) = 1 ([{fd=15, revents=POLLHUP}])
  read(6, 0x98be900, 4096)                = -1 EAGAIN (Resource temporarily 
unavailable)
