 * A workaround for what I think is a GTK+ bug:
 *  If a dialog is hidden using gtk_widget_hide(),
 *  and was iconified before, it is still present
 *  in the window_list and can be deiconified by
 *  the user later. All subsequent calls to
 *  gtk_widget_hide() will then fail since the state
 *  of the widget is still INVISIBLE.
 *  Calling gdk_window_withdraw() seems to solve this.
 *                                         --Sven
