 I started removing files as you've suggested and the minimal
 condition that triggers a crash is at least one non-mbox file.

Thanks, fixed: http://hg.dovecot.org/dovecot-2.0/rev/b74dfa49692b

A backtrace can't really show why it crashed with this. Something wasn't
freed for some reason. Can you still reproduce this? I'd like to know of
a way to reproduce this. Maybe you can copy this problematic user's
mailboxes to a test user and keep deleting stuff until you see what
triggers it?
