	* app/plug-in/gimppluginprocedure.c
	* app/plug-in/gimptemporaryprocedure.c: don't just free the 
return
	values when running procedures asynchronously. Instead examine
	them and display the error message if there's one.

	* app/plug-in/gimppluginmanager-call.c
	(gimp_plug_in_manager_call_run_temp): return NULL if
	procedure->plug_in is not set.

	* app/plug-in/gimpplugin-message.c: comment.
