* clutter/clutter-effect.c: (clutter_effect_closure_destroy): Do not remove the actor from the behaviour; the behaviour is an internal detail of the effect, and it will remove the actors anyway when finalized when g_object_unref() is called. This should guard against actors being destroyed while an effect is running.
