Sent an e-mail off as was detailed here:
http://wiki.dovecot.org/MboxProblems for crashes but I also wanted to
see if any of you folks had insight into the issue.

Dovecot is crashing on a certain user inbox which is in mbox format as
well as one of the users other mbox files. The crash doesn't exactly
match what is listed in the aforementioned wiki page, so I thought their
might be some other insight into this process or how to fix it.

Here is the error in the log files:

Any ideas or thoughts?
