I haven't heard anything on this bug.  Is this a bug?  I'm using dovecot 
1.1.2 with the following patch applied:

http://hg.dovecot.org/dovecot-1.1/rev/d674c05d725d

Another section from my logs. I know the backtrace is just numbers, let 
me know how to compile to get more useful information if you need it. 
So far no one is beating down my door, so I don't think users are seeing 
any ill effects.  But I would sleep better knowing why it's happening.

I just switched over to dovecot 1.1.2 on our live system last night. I'm
seeing the following errors in the logs:

Aug 19 10:01:03 goku dovecot: [ID 107833 mail.crit] Panic: IMAP(elevin):
file in
dex-sync.c: line 39 (index_mailbox_set_recent_uid): assertion failed:
(seq_range
_exists(&ibox->recent_flags, uid))

I did apply the assertion fix that Timo sent out.
