[MlMt] Empty smart mailbox not really empty

[John Cooper]

I have a small collection of smart mailboxes that only point to 
particular folders on my mail server. They have no conditions, only a 
setting under the Mailboxes tab that specifies the target folder like 
so:

Any of the following mailboxes
	[server] > Tickets

All of them work (that is, display exactly the messages I see listed 
when I click on the corresponding IMAP mailbox in my Sources list) 
except for the one I created this morning. That smart mailbox displays 
empty, although the target IMAP mailbox has four messages. It's stayed 
empty even after repeated synchronization, restarting MailMate, and 
updating MailMate from build 5347 to 5358.

What's bizarre is that when I dragged a message from my Inbox to the 
smart mailbox, the mailbox is still empty--although the moved message 
does appear in the corresponding mailbox in my Sources list. In other 
words, I can use the smart mailbox as a destination, but it still won't 
show its contents.

Of course, I've used the Conditions tab in the Edit Smart Mailbox dialog 
to try to find an alternative way to specify the IMAP folder without 
success.

Any ideas?
