dovecot - Jan 2003 - Assert in imap-bodystructure.c

First let me thank you for my initial newby question about poping
from a pop3 server and delivering into my Dovecot maildir folders.

Now I'm getting an assertion in imap-bodystructure.c and one of 
my imap folders is now inaccessable. I think the two are related.
Whenever I select the folder from my email client (kmail) I get
two log entries in the dovecot log of the format:
    "imap-master: <date>Error: child <pid> (imap) killed with
signal 6"

Also in the log are several lines with an assertion failure. I've included
a portion of the log below.

I am running dovecot 0.99.5.

Thanks,
Brad

Annoying, you're the second person now who sees this. Is this Linux/x86
system? Maildir?

Would it be possible for you to send me that mail folder's indexes? They
contain some headers of the mails (from, to, subject, ..) and are
located in ~/Maildir/.folder/.imap.index* or
~/mail/.imap/folder/.imap.index*. I didn't find any obvious reason for
this problem last I looked, so getting those indexes would help to find
why they're corrupted.

Anyway, fixing this would most likely work by just deleting those index
files. If that didn't help either, it's some mail in there that Dovecot
doesn't like for some reason.
