dovecot - Dec 2010 - All messages in double in a virtual mailbox.

Hello,
 I've got some virtual maiboxes that are configured as follows :

 !RealMail.Sent
 RealMail.Sent
   all

 In all those mailboxes, all the messages appears in double. I don't 
 think it's the expected behaviour, but I perhaps missed something.

 Here's my dovecot -n :

 Thanks for your help

!RealMail.Sent that already includes that mailbox. So when you give it again
without '!' it gets duplicated.
