This problem don't occur very often.  So far only seven times since Jan 
31 and everytime I have done something which fixes it magically. 
Yesterday it was a mail which had only base64 encoded data in it.  I was 
able to move that mail to another folder and back using thunderbird. 
I've no idea why have the problem has appeared more frequently during 
the last couple of days.  Here are the timestamps when it happened and 
first and last log entry.  Altogether 315 cores so far.  I started to 
use 1.1 b14 Jan 23 so it took a while before it happened.  I'm the only 
one using this environment.
