Yep. The problem is that the message is actually deleted from gmail's servers, but the title of the message and the message ID is still reported as being available. So the mail client says "hey, this is a new message!" and shows you the title. But when you try to look at it, the message is blank (because it's actually been deleted). And the mail client can't mark it as read (because it's been deleted). The message itself is gone, but the title is still hanging around in the list of available messages on the server.
