This happens if message headers are modified in mbox. Looks like in your
case something added 30 bytes there. Could there be something else
besides Dovecot modifying the mbox? Or if Dovecot added/modified some
headers that aren't hidden, I'd like to know about that too. The hidden
headers are: Content-Length, Status, X-IMAP, X-IMAPbase, X-Keywords,
X-Status and X-UID. Hmm. Maybe X-UIDL should be added to that list..
Yes, I'll do that.

Anyway, I think I should also add some checks for this instead of
letting it assert-crash..
