	* gtk/gtkdnd-quartz.c: (gtk_drag_drop_finished): Run
	gtk_drag_source_info_destroy in an idle, workaround for bug
	#501588, that makes any code that uses the context returned from
	gtk_drag_begin() crash, like treeview/iconview dnd.
	(GdkDragSourceOwner::provideDataForType): only use the data if we
	got any.
