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.
