ChangeLog: 

This should prevent the crash in #8109 by stopping an invalid message from
getting in the queue.  There is still a problem farther up from here in that
an invalid message shouldn't get this far - hopefully this will help track it
down by providing a message at the time the issue happens instead of crashing
later.  Fixes #8109.
