dovecot - Jan 2013 - Can't rename mailboxes, any ideas on how to fix?

I am running Dovecot 2.1.12 under FreeBSD, and I use Outlook 2010 with imap
to connect to my server.   I know I used to be able to rename mailboxes, as
I do this every year at year end, but when I went to rename some mailboxes
the start of this year, blamo up popped the message "CANNOT Renaming not
supported across conflicting directory permissions".

 Then only thing that has really been updated here, is Dovecot itself, as I
know the FBSD port updates when new versions are released.  Any clues on
what may have caused this, or how to best correct it?

What mailbox format? What are you renaming and where? What are those
directories' permissions? Anyway newer Dovecot versions are a bit more
strict about directory permissions being same in source and destination.
