I have a new installation of Dovecot 2.1.12 and cannot select the Inbox without getting this error:

c select inbox c NO [SERVERBUG] Internal error occurred. Refer to server log for more information. [2013-01-16 18:22:13]

Here's the server log: dovecot[15643]: imap(u1): Error: Failed to autocreate mailbox INBOX: Mailbox already exists

Auto create settings are currently set to 'no' -- when they were set to create, the problem was the same. Passwords are currently plaintext for testing purposes -- Imap authentication works.

It's running on OS/X 10.7.3 Our config is below. Thanks for any suggestions...
