	* app/widgets/gimpdnd.c (gimp_dnd_data_drag_begin): remember for
	which GdkDragContext the icon_widget was made.

	(gimp_dnd_data_drag_end): destroy the icon_widget only if it was
	created for this GdkDragContext. Fixes broken DND icon_widgets
	when dragging the same source again while the old icon_widget is
	still floating back from an unsuccessful drop. Fixes bug #139337.
