	* app/widgets/gimpcontainertreeview-dnd.c
	(gimp_container_tree_view_drop_status): always call
	gdk_drag_status() before returning FALSE.

	(gimp_container_tree_view_drag_motion): never return FALSE, an
	impossible drop location is now reported by calling
	gdk_drag_status() above. Always returning TRUE makes sure
	gimp_container_tree_view_drag_leave() is called unconditionally
	and can remove the scroll_timeout set in drag_motion().

	Fixes bug #152193 and many other obscure DND crashes caused by the
	scroll_timeout being invoked after the widget is destroyed.
