Does it include "UIDVALIDITY changed" error before the assert? I finally
got around to fixing that:
http://hg.dovecot.org/dovecot-1.1/rev/471b0096b579

I'm not sure about this, but these patches add some more asserts to
cause it to happen earlier:

http://hg.dovecot.org/dovecot-1.1/rev/983f82053800
http://hg.dovecot.org/dovecot-1.1/rev/336eabeae7fd
http://hg.dovecot.org/dovecot-1.1/rev/a1a14d67b15d

I've added some debugging code to my code to figure out why this is
