dovecot - Jan 2007 - unable to read mail - file istream-raw-mbox.c: line 499...

Greetings all,
I (nor anyone else) am suddely unable to read mail.
Dovecot dumps the following in it's log:
# BEGIN LOG ENTRIES #
dovecot: Jan 07 18:15:52 Info: imap-login: Login: user=<username>, 
method=PLAIN, rip=::1, lip=::1, TLS
dovecot: Jan 07 18:15:52 Error: IMAP(username): file 
istream-raw-mbox.c: line 499 (istream_raw_mbox_get_body_size): 
assertion failed: (rstream->mail_size != (uoff_t)-1)
dovecot: Jan 07 18:15:52 Error: child 1584 (imap) killed with signal 6
# END LOG ENTRIES #

NOTE: 'username' represents the users name at that time.

The users subscribed to folders all show up. But no mail is visable.
Dovecot is leaving username.lock files in /var/mail as well. It doesn't 
do this
on my other servers running dovecot. They are using older versions of dovecot
tho.
Does anyone know what might be causing these problems?

Relavent info follows:
Dovecot version: 1.0.r15
OS: freebsd-5.5

Thank you for all your time and consideration.

SOLVED

I was able to cure the problem by removing:

mail_read_mmaped = yes

from dovecot.conf.
Now all works as expeted/ intended.

woohoo! :)
