[Dovecot] Clients show .subscriptions folder

Since upgrading from dovecot-2.1.rc1 to dovecot-2.1.rc3, some clients
are showing a .subscriptions file in the user's mbox path as a folder.

Some clients such as T'bird on Mac OS X create this file listing
subscribed mbox files. Other clients such as T'bird on Windows XP show
this file as a folder in the folder list even though it cannot be
accessed as a folder (dovecot returns CANNOT Mailbox is not a valid
mbox file).

I think this may be a result of uncommenting the inbox namespace in
conf.d/10-mail.conf
<http://hg.dovecot.org/dovecot-2.1/rev/2c8d39467f21>.

Is there a way to supress exposing this file to clients that don't use
it?
