After deleting the .imap/ directory, remove all X-UID headers from  
the mbox file. I'm guessing it contains some very high UID numbers  
and Thunderbird doesn't understand them and sends negative numbers  
instead (this is actually a TB bug).

If that didn't help, show me the command Thunderbird sends. Use eg.  
Wireshark or rawlog (see http://dovecot.org/bugreport.html).

Originally it could have been caused by invalid X-UID headers, but  
not anymore.
