[Dovecot] \Noselect eliciting bug?

Timo, examine these two simplified sets if you will.

This, is a properly working $inbox folder:

d /home/david/.maildir /home/david/.maildir/dovecot.* d /home/david/.maildir/cur d /home/david/.maildir/new d /home/david/.maildir/tmp /home/david/.maildir/subscriptions

This one is not, $inbox becomes \Noselect:

d /home/david/.maildir /home/david/.any-file /home/david/.maildir/dovecot.* d /home/david/.maildir/cur d /home/david/.maildir/new d /home/david/.maildir/tmp /home/david/.maildir/subscriptions

i can make directories willy nilly starting with a dot, but a -file- starting with a dot breaks my mailbox. it doesn't affect any other folder, just $inbox
