	Fix #152760, Christian Persch:

	* gtk/gtkaboutdialog.c (gtk_about_dialog_finalize): Don't free
	private data.
	(gtk_about_dialog_set_translator_credits): Recommend the msg
	id translator-credits.
	(display_credits_dialog): Show translator credits if they're
	translated, not if they're untranslated.
