	* gtk/gtkfilechooserutils.c (delegate_notify): Use
	the less efficient g_object_interface_find_property () instead
	of the param_id range check, since the GParamSpecs we're
	dealing with are the overridden onces on the interface, whose
	param_id is always zero.  (#145312, Alex Roitman, fix proposed
	by Owen Taylor)
