[Dovecot] Crash and Assertion Error

I've attached two backtraces, one from a segfault and another from an
assertion error in imap. I've seen a couple of the same assertion and
this is the only segfault. It looks like they could be related. They
both have to do with indexing anyway...
The code is from CVS as of May 30.
The segfault happened while imap was doing searches for my pine filters.
I've also noticed that in pine, if I expunge a lot of mail that is
spaced out through my mbox, it usually gets the headers mixed up.
What I mean is that I will open one email and get the body from another.
Just mentioning this in case it has some bearing. I'll be trying some
things out to see if I can figure out why this happens.
Can't think of any more useful info, I need sleep.
