Yes, UIDVALIDITY changes currently causes this assert. I should fix that
some day. They don't really harm much since even without the panic the
client would be disconnected anyway.

So the main problem here is why is the UIDVALIDITY changing? Do your
users have direct access to the mbox files?
http://wiki.dovecot.org/MboxProblems describes the problem.
