dovecot - Nov 2009 - FW: Panic: Message unexpectedly expunged from index

Nevermind.  I figured it out.  I left off the INDEX command.  Sorry to spam
the mail list :(

Here is my mail_location for future reference / searches:

mail_location
mbox:/var/spool/mail:INBOX=/var/spool/mail/%u:INDEX=/var/indexes/%u

Hello,

I just installed Fedora 11 with Dovecot 1.2.6 and am now seeing a steady
stream of these in maillog:

Nov 15 15:52:03 sendmail dovecot: POP3(<username>): Panic: Message
unexpectedly expunged from index
Nov 15 15:52:03 sendmail dovecot: POP3(<username>): Raw backtrace: pop3

Nov 15 15:52:03 sendmail dovecot: dovecot: child 26792 (pop3) killed with
signal 6 (core dumps disabled)

I see nothing about this in the mail archives or on the internet!
What could be happening and how do I fix?
I'm also seeing lots of these:

Nov 15 11:26:24 sendmail dovecot: POP3(<username>): Log synchronization
error at seq=12646,offset=172 for /var/spool/mail/.imap/INBOX/dovecot.index:
Extension introduction for unknown id 1
Nov 15 11:26:24 sendmail dovecot: POP3(<username>): fscking index file
/var/spool/mail/.imap/INBOX/dovecot.index

Here are the only things I messed with in dovecot.conf:

protocols = pop3
mail_location = mbox:/var/spool/mail:INBOX=/var/spool/mail/%u
mbox_very_dirty_syncs = yes

Thanks in advance,

Cliff

You shouldn't use /var/spool/mail as the mail root anyway. I suppose
you're using only POP3, but if you ever happen to (even accidentally)
enable IMAP access the above configuration may give access to other
users' mails (although I suppose the filesystem permissions will prevent
that if you're using system users).

In any case, I'd suggest something like:

mbox:/var/empty:INBOX=/var/spool/mail/%u:INDEX=/var/indexes/%u

Would it be better to just drop the mbox part?  Like this:

mail_location = INBOX=/var/spool/mail/%u:INDEX=/var/indexes/%u
