Evince cannot open external links with Firefox

[Uwe Lück]

I could open weblinks from Evince using Firefox under Ubuntu 10.04 since summer 2011 until today (2012-05-09), when I received "permission denied" the first time. https://wiki.ubuntu.com/DebuggingApparmor and /var/log/kern.log indicated a problem with AppArmor. Following https://bugs.launchpad.net/apparmor/+bug/605586, I found /etc/apparmor.d/abstractions/ubuntu-browsers as of – I think it was 2009, now that I changed it I cannot retrieve the former modification date, funny ... and there:

  # this should cover all firefox browsers and versions (including shiretoko
  # and abrowser)
  /usr/lib/firefox-*/firefox.sh PUx,

Instead, I found /usr/lib/firefox/firefox.sh, and so essentially changed the last line into

    /usr/lib/firefox*/firefox.sh PUx,

(just removing hyphen) which solved the problem.

So this is more basic than #605586 in that exo-helper is not involved, while the latter bug report provided the idea that the problem is in ubuntu-browsers.

The reason may have been that I called a major upgrade yesterday (2012-05-09) after many weeks. I took me to linux-generic 2.6.32.41.48 and from Firefox 10.0.2 to Firefox 12.0 ...

The same day (today), exactly the same problem with Evince and Firefox was reported by a different Ubuntu user in German: http://forum.ubuntuusers.de/topic/evince-oeffnet-externe-links-nicht/
