May I suggest a replacement test that does not use self.client? something along the following:

```python
@patch('bedrock.newsletter.views.l10n_utils.render')
def test_update_allows_good_tokens(self, mock_render):
    token = unicode(uuid.uuid4())
    request = RequestFactory().get('/')
    updated(request)
    eq_(mock_render.call_args[2]['token'], token) 
```

similar for the method below, except with ```token = 'the dude'``` and ```eq_(mock_render.call_args[2]['token'], None)```
