offlineimap crashes on gmail sync

[ogi]

Hi,

I'm experiencing problems during my intial sync from gmail. The program 
consistently crashes trying to download a particular message. The problem 
appears both with the stable and the git versions.

I'm attaching the stacktrace, but not the debug logs; using -d makes the 
problem go away (the sync of the problematic message still fails, but the 
program goes on syncing the rest), so it seems to be some kind of a race 
condition. Please let me know if I you need me to make the debug logs 
available (the imap one's around 2MB so I'm not attaching it here), and which 
ones do you need in particular.

Cheers,
Ognjen
