Bug#1127710: thunderbird: apparmor profile prevents launching thunderbird with gdk-pixbuf >= 2.44.5

[Shawn K. Quinn]

After a reboot I was finally able to restart Thunderbird. I took the 
drastic step of `rm /etc/apparmor.d/usr.bin.thunderbird` (I have backups 
if I need to restore it) as aa-complain said there was a syntax error in 
that file. (Or, most likely, it will be reinstalled with a later 
version, hopefully with this syntax error fixed.)
