+Subject: [PATCH] clutter/actor: Don't emit focus signals during destruction
+
+We rightfully unset the stage focus when the focus actor is destroyed,
+which in turns results in the ClutterActor::-key-focus-out signal being
+emitted on an actor that is no longer fully valid.
+
+Avoid that emission, so consumers don't have to deal with half-disposed
+actors in their handler.
