This looks a lot like the issue I reported last month at
<http://dovecot.org/pipermail/dovecot/2008-April/029991.html>
which see for configuration details.

At that time, I thought the problem was due to a conflict between
Postfix adding a message to the mbox while dovecot was expunging
messages. I have since seen the problem one more time apparently
precipitated by two remote boxes accessing the same mailbox via
separate dovecot processes simultaneously.

I have since added

 pop3_lock_session = yes

to the dovecot configuration, and I have seen no further problems,
but it's only been 2 weeks since I made the above change so it's
too soon to know for sure.
