    [gail] Proper connection to a toplevel window destroy signal
    
    Only connect to the destroy of a toplevel window if it was
    really added to the toplevel list of windows.
    
    The destroy callback was added to remove the window from
    the toplevel list. The callback doesn't cause a error,
    but would iterate on the toplevel list without success.
