'nother bug two bugs:
 * Adding  causes the masthead and profile tabs to completely break (when on your user and activity pages) and nothing whatsoever to show up on your Message Wall page.
 * your Message Wall Greeting page isn't transcluded onto your Message Wall.

As an aside, User Talk no longer redirects to the Message Wall equivalent, even if Message Walls are enabled! Hopefully this stays the case.
