Odd indeed. I've used tb on and off, and never seen that.
One of you might perhaps try to change all the uidvalidity values. The current values are legal, but they're all equal, which isn't normal. If you make sure that mailboxes.uidvalidity has different values in each mailbox, does tb behave differently?
(Tb will go out of its mind the first time it connects afterwards. That's expected: Changing uidvalidity invalidates all clientside caches.)
