That's just too bad.
AFAICS, we only ever set mouse_face_window to either nil or a window
object. This case seems to imply that its value was neither, because
clear_mouse_face verifies it's non-nil before calling show_mouse_face.
Therefore, it's important to look at the contents of that object,
because the only value other than nil or a window could be garbage,
which would hint on some memory management problem. Or maybe I'm
missing something.
