Evince would not start over SSH X-forwarding

Evince, which is the primary PDF and PostScript viewer on Ubuntu, recently stopped working on my Ubuntu/Natty (11.04) over SSH X-forwarding. It works flawlessly inside 'gnome-session'. But, would not run as a regular application (e.g. xpdf or gv) over X-forwarded SSH.

After digging up a little bit, I found a lots of these message in my
dmesg output:

[1305902.871825] type=1400 audit(1310620543.587:75): apparmor="STATUS" operation="profile_remove" name="/usr/bin/evince" pid=20166 comm="apparmor

It was obvious that apparmor [1] was blocking Evince to run outside Gnome session over SSH. A solution to disable the AppArmor block on Evince over SSH connection was suggested here [2]:

#inside the gnome-terminal
sudo ln -s /etc/apparmor.d/usr.bin.evince /etc/apparmor.d/disable
sudo /etc/init.d/apparmor restart

And voila! Now Evince can again be launched over SSH.
