[Dovecot] Strange messages?

[Knute Johnson]

The following messages show up in the output of a script that does some 
backup.  This too is new with the upgrade to Ubuntu server 12.04.1 and 
dovecot 2.0.19.

Anybody know what would generate these sorts of messages?  Where or what 
would cause them?

WARN: Duplicate profile 'Dovecot POP3', using last found
WARN: Duplicate profile 'Dovecot Secure POP3', using last found
WARN: Duplicate profile 'Dovecot IMAP', using last found
WARN: Duplicate profile 'Dovecot Secure IMAP', using last found

Thanks,
