redhat-config-services currently has an "Exit" button in the toolbar. The GNOME Human Interface Guidelines (http://developer.gnome.org/projects/gup/hig/) advise against such a practice: "Don't add buttons for Help, Close or Quit to your toolbar by default, as these are rarely used and the space is better used for more useful controls. Similarly, only provide buttons for Undo, Redo and the standard clipboard functions if there is space on the toolbar to do so without sacrificing more useful, application-specific controls." Also, no other Red Hat tools provide an Exit button on the toolbar, so I suggest for it to be removed from redhat-config-service if just for the sake of consistency.
fixed in redhat-config-services-0.8.3-2
