    [Gtk.Tasque] Imitate tooltip in AppIndicator using a MenuItem.
    
    This workaround was originally proposed in Alessio Caiazza's patch
    to his bug report about the missing tray in Ubuntu/Unity:
    https://bugzilla.gnome.org/show_bug.cgi?id=649670
    
    Note: Due to another bug the tooltip is currently not updated and
    always states "Tasque Rocks".
