Warning: mdbox /dane/domeny/mejor.pl/mail/marcin/mdbox/storage:
rebuilding indexes

This is reproducible by me. I've made test namespace, then in
Thunderbird i've created new subfolder, then i copy (ctrl+ mose move ;)
) ~700 mails from other folder. When i try to go inside this subfolder i
gets those errors, thunderbird shows only 33 emails. Those emails can't
be deleted.

Regards!
