Any idea how I could reproduce this? I've been running my IMAP stress
test for a while now waiting for this assert to fail, but so far it
hasn't. Maybe it needs some special kind of a mail or some other
specific condition.
Anyway I did some fixes, do these change the crash to an error message?

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.
