Bug#900210: thunderbird: Thunderbird AppArmor config disables ability to send entirely

[Vincas Dargis]

I've reproduced it.

This is yet another sign how we need use more variables in AppArmor, and 
it needs to be fixed not only for Thunderbird, as $TMPDIR change will 
affect other confined applications too.

I'll continue discussion in AppArmor mailing list to see how to approach 
it better.

P.S. Also, waiting for AppArmor 2.13 in Debian ;)
