[MlMt] r5635: cannot move messages

[Eric Sharakan]

Hi, this is a much more serious problem than the one I just reported: I 
cannot move messages between mailboxes.  It doesn't matter whether I use 
drag and drop, the Cmd-Opt-T keybinding, or the Message->Move to 
Mailbox... menu item, the message simply stays put.

This only seems to be an issue for 2 of the 5 accounts I have 
configured.

Any thoughts?

Thanks.
