	* app/plug_in.c: be a bit more verbose in the "Plug-In crashed"
	message: Warn the user that Gimp's internal state may be messed
	up and that the safe way is to restart Gimp.
	Unified all plug-in error messages.

	* libgimp/gimp.c: also changed to messages that the Gimp is using
	a newer/older wire protocol than the plug-in.
