The problem was that STATUS command synchronized the index and maildir,
so that the next time mailbox was opened Dovecot thought the new/
directory was already synchronized so it didn't bother looking into it.
But that also meant that it didn't move the mails to cur/ and their
recent flag state was kept..

Fixed now in CVS, and upcoming beta4.

This is done on purpose. The filenames keep changing and only the base
filename is important. Dovecot just tries to optimize file opening a bit
by keeping the last known full filename in the dovecot-uidlist file.
