[Dovecot] Undeserved permissions error with g+s folder permissions

I have a (mbox/IMAP) directory under my mail directory with these 
permissions:

drwxrws--- 4 tlhackque mail 4096 Dec  1 10:34 Vendors/

It contains a subdirectory:

-rw-rw---- 1 thlackque mail 84805345 Dec  1 10:34 Vendors/AVendor

If I try to rename the AVendor folder (client is Thunderbird 17.0), I 
get this error:

     Unable to rename across conflicting directory permisssions

If I chmod g-s Vendors, the RENAME command succeeds.

I shouldn't have to do this...
