Due to some self inflicted system injuries (I blame pulseaudio) I hit his error. The reason for this is the gnome-settings-daemon is not working so GTK does not pick up the correct icon theme so it defaults back to hicolor, which does not have icons for "window" or "gtk-missing- icon". These icons exist in the gnome-icon-theme package and in GConf this is the default, and is also in Clearlooks, which is the default for the overall theme.
