you would probably need to ask debian or apparmor on their forums or irc.  
#apparmor is on oftc network,  #debian is on freenode.  

Have you tried adding that path to the thunderbird profile? I guess it would 
need read write execution permisions?  You would probably want to do it the 
most secure way though and I'm no expert.

I know I have to do something similar for hexchat certificate files every now 
and then. After I compare the key online I have to add the path to the profile 
and give it an r, at the end.  In your case you will also need execute  so rx, 
at least.  See if there is other /usr/bin lines in the profile to compare.

Then after you save the new profile in terminal aa-disable the profile and 
aa-enable it and see if you get any errors or see if it works.
