[Maciej Stachowiak <mjs eazel com>]

I'll commit this to stable tomorrow unless anyone objects. The
ChangeLog should explain all.

+	* libgnomeui/gnome-init.c: (gnome_add_gtk_arg_callback),
+	(gnome_init_cb), (gnome_init_with_popt_table), (gnome_init): Just
+	return silently if GNOME is already initialized, rather than
+	g_return_if_fail()ing. This is needed because there is no way to
+	even know if GNOME is already initialized, and there are times
+	when two pieces of code may both have valid reasons for wanting
+	GNOME initialized, for example if a GNOME app has embedded Python
+	and wants the embedded python scripts to be able to use the
+	Python/GNOME bindings.
