Solve the following python programming problem given the following code:
@ mock.patch ('oslo_i18n.translate') 
@ mock.patch ('nova.i18n.get_available_languages') 
def test_safe_exception_translated(self, mock_languages, mock_translate) : 
    def fake_translate(value, locale) : 
        return "I've been translated!" 
mock_translate.side_effect = mock_languages 
    safe_exception = exception.NotFound ('Should be translated.') 
    safe_exception.safe = True 
    safe_exception.code = 404 
    req = webob.Request.blank ('/') 
    def raiser(* args, **kwargs) : 
        raise safe_exception 
wrapper = nova.api.openstack.FaultWrapper (raiser) 
    response = req.get_response (wrapper) 
    mock_translate.assert_any_call ('Should be translated.', None) 
    self.assertIn ("I've been translated!", response.body.decode ('UTF-8')) 

    
    

    Fix the buggy line: mock_translate.side_effect = mock_languages
