When the Dovecot 1.0.rc19 IMAP server encounters X-UID headers with gaps in them, it hangs indefinitely. I've attached a sample mailbox (in mbox format) which repeatably exhibits this behavior. The mbox contains only three messages with the following X-UIDs in order: 774, 785, 787. If I remove the X-UID headers from each message, Dovecot handles the mailbox without any problems. UW-IMAP is able to handle the sample mbox _with_ X-UID headers.
You're the second person to report this today, and I also noticed this myself today. I guess I did something in rc18-rc19 which made this problem appear more often. Anyway these patches should fix it:
