We have this weird hack in the panel now where we make the panel look for the redhat-main-menu icon instead of the gnome foot. These days, though, this icon is themeable under tha name "gnome-main-menu". So, we should rename redhat-main-menu to gnome-main-menu. See: http://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=100407
Fixed in redhat-artwork 0.93-1.
