Bug 1299 - clutter_score_remove will segmentation fault if

Browse Source 
timelines are more than 52 and continue to remove them

	* clutter/clutter-score.c (traverse_children): Don't destroy the
	entry in the handler for REMOVE_BY_ID. It will be removed again
	anyway in the call to g_node_traverse. This was causing a
	crash. Thanks to zhangwei for spotting.
