Comment 3 for bug 940701

BTW, just to add that that g_object_set_qdata warning is https://bugzilla.gnome.org/show_bug.cgi?id=661155 which has been fixed in git.gnome.org repository (http://git.gnome.org/browse/pygobject/commit/?h=pygobject-2-28&id=42d871eb0b08ee6d55e95cc7e4b90844919555b9), but new release of pygobject has not been made yet.
