[Dovecot] "too little data" error still occurring in 1.0.10

Greetings-

I'm running dovecot 1.0.10, but am seeing the "too little data" error that was supposedly fixed in 1.0.9. Not sure how long it's been going on.

I have a straightforward mbox setup, and am using Thunderbird to check my inbox. It can't read the box. The log fills up with these messages:

Feb 8 23:24:43 chilled dovecot: imap-login: Login: user=<mike>, method=PLAIN, rip=##.##.##.##, lip=##.##.##.##, TLS Feb 8 23:24:43 chilled dovecot: IMAP(mike): FETCH for mailbox INBOX UID 1644 got too little data: 4254 vs 4262 Feb 8 23:24:43 chilled dovecot: IMAP(mike): Disconnected: Disconnected

Let me know if there's more info needed.
