dovecot - Jul 2006 - moving public folders to private Trash

Using Thunderbird 1.5.0.4 against dovecot beta9:

If a user has Thunderbird configured to move deleted messages into a Trash
folder,
then the user cannot delete folders in a public namespace.  There is no problem 
deleting messages.

Thunderbird says:
"The current command did not succeed.  The mail server responded: Can't
rename
mailbox to another storage type."

All mailboxes (public and private) are maildir format.

Users can successfully delete folders from their own private areas, and the
folders
then appear as subfolders of the Trash folder.

Also, users can reconfigure Thunderbird to delete messages immediately instead
of
moving them to trash and then successfully remove public folders.

Also, users can move public folders within the public namespace.  So I think the
problem boils down to the inability to move a folder from a public namespace to
a
private one, which is what happens when Thunderbird is configured to move
deleted
messages to a Trash folder.

I have the same problem with dovecot rc10 and Thunderbird 1.0.5.7. Apart
from changing the users settings to delete messages immediately has
anyone found a solution to this problem?
