dovecot - Aug 2005 - Sig11 and some corrupted indexes after 1.0-stable -> 1.0.alpha1

I just upgraded my production box from 1.0-stable to 1.0.alpha1.  I've
noted some new errors in my dovecot logs:

Aug 28 23:23:56 cliff dovecot: IMAP(rsferra): Corrupted index cache
file /mail/mcad.edu/rsferra/Maildir/.Sent Items/dovecot.index.cache:
indexid changed
Aug 28 23:33:57 cliff dovecot: IMAP(acarr): Corrupted transaction log
file /mail/mcad.edu/acarr/Maildir/.Deleted Messages/dovecot.index.log:
unexpected end of file while reading header

I'm not too worried about those, as I'm hoping they'll go away once
all the indexes have been rebuilt.  However, these are a bit more
disconcerting:

Aug 29 09:07:35 cliff dovecot: child 22484 (imap) killed with signal 11
Aug 29 09:07:36 cliff dovecot: child 22488 (imap) killed with signal 11

I don't see any other errors in the logs around those messages.

Platform:

Gentoo 2005.1, 2.6.10 SMP kernel, mail stored on XFS file system

Any thoughts?

A co-worker reported to me an error when attempting to copy a message
to the "Trash" folder.  Squirrelmail reported this:

ERROR : Connection dropped by imap-server.
Query: COPY 243 "Trash"

I asked him to reproduce this while watching the logs.  As soon as he
deleted the message (and squirrelmail attempted to move it to the
"Trash" folder) I saw one of the above entries.

This is the message in question:
http://cliff.mcad.edu/dovecot_bad_message.txt

It seemed to be happening with other messages, too, but that's the
only one I identified absolutely.

I dropped back to 1.0-stable and the segfaults stopped and IMAP became
speedy again.

Could you try current CVS version?
