dovecot - Jan 2014 - Panic: file mailbox-list-maildir.c: line 133: unreached

Hi

I am using dovecot 2.0.9 on CentOS 6.4

The following error appears in the logs when users connect to the imap  
server using MACs. All
other clients that I tested work fine.

I don't know what to do to allow MAC users to use the system. Can anyone
help?

Thank you,
