Comment 12 for bug 471542

the issue could be similar to bug #562509 and due to icons watching, upstream dropped that in http://git.gnome.org/browse/gdm/commit/?h=gnome-2-30&id=744557f87c84398860c102ba8f8d10790487ae32 which got backported in that upgrade but some of the distro changes seem to do something similar

Robert, could you check if that's an issue and if your changes need similar cleaning?
