It is possible for the stack to run into this problem if you have a 
particularly complex list of read-versus-unread messages. (Yes, it's a 
bug.) The easiest thing to do is simplify the message list. Doing "mark 
all messages as read" will essentially reset everything for that group. It 
may be that it's still remembering that you haven't read messages which 
aren't even around any more.
