Hey Aki,
Can you please include excerpt of your logs too? There should be "Panic: ..something..." there. I just sent those over in a reply on my original mail. Also note that dovecot-antispam seems to be involved somehow, as noted in that mail.
also bt full is more useful than just bt. Learn something new every day. Thanks! Full trace below.
