It would seem to me that the set should fail.
def test_none(self):
        """Ticket #1124."""
        signal.medfilt(None)

Not sure how to do this but I guess it is possible that the error is
not a sigfualt or medfilt could return a more meaningful error because
None is not a good argument. Volume=None > gets converted with
numpy.atleast_1d(*arys) which returns array([None], dtype=object).

So should the test use an expect exception? Or whats the fix?
