[RCU] Trash problem with 0.6

Hello, since the upgrade from 0.5.3 to 0.6 I have a problem when some users try to delete messages in their INBOX. The error is:

"UID COPY: Client tried to access nonexistent namespace. (Mailbox name should probably be prefixed with: INBOX.)."

This appens only on mailbox that have INBOX as namespace, I use Dovecot 2.0.x as IMAP server so when it is configured as:

namespace { inbox = yes location = prefix = INBOX. separator = . type = private }

On servers without namespace configured I have no trouble (always Dovecot as IMAP server)

I can fix the error simply by Settings, Special Folders, "Save". When I save settings the trash icon appears in the folder list and the trash works.
