Yeah, that definitely looks like a bug!  I've CC'd Timo to grab his attention :)

Hey Timo, it works right in Cyrus :p

. list () "" (INBOX INBOX.Trash INBOX.Archive) RETURN (STATUS (UNSEEN))
* LIST (\HasChildren) "." INBOX
* STATUS INBOX (UNSEEN 0)
* LIST (\Trash) "." INBOX.Trash
* STATUS INBOX.Trash (UNSEEN 0)
* LIST (\HasChildren \Archive) "." INBOX.Archive
* STATUS INBOX.Archive (UNSEEN 0)
. OK Completed (0.010 secs 113 calls)

(I have specialusealways configured, doesn't seem to break anyone)

Bron.
