I believe this is an error in our Kolab integration rather than with  
the IMAP library itself.  The metadata retrieval call in the library  
is doing nothing more than taking the "mailbox" input and escaping it.  
  ("*" is a valid mailbox name, albeit non-optimal, so sanity checking  
is the responsibility of the consumer).

I'll pass the report along so that this is fixed in the Kolab  
integration code.
