I begin to understand the problem. I think dbus-glib miss a function
like:

void
dbus_g_object_type_uninstall_info (GType object_type,
				 const DBusGObjectInfo *info)
{
  g_return_if_fail (G_TYPE_IS_CLASSED (object_type));

  _dbus_g_value_types_init ();

  g_type_set_qdata (object_type,
		    dbus_g_object_type_dbus_metadata_quark (),
		    NULL);
}

To add in dbus-gobject.c at line 1534 (dbus version 0.50)
