[dovecot] Assert in imap-bodystructure.c

[Brad Figg]

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
