Confirmed. The issue is with evince-gtk and mozplugger together. Installing evince fixes the problem but removes xubuntu-desktop which is a whole other problem.
Either mozplugger/evince-gtk need to be fixed or xubuntu needs to depend on evince-gtk | evince. -- mozplugger and evince-gtk can't open pdf file in Xubuntu https://launchpad.net/bugs/84233 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
