"TypeError: 'NoneType' object is not iterable" inside tests

Issue #64 new

Hi! I just upgraded to the latest version of johnny-cache (tip) as a part of porting our site to Django 1.4. Problem is, our tests stop running when the two middleware classes are enabled. Here's the stacktrace:

{{{ (<project>)~/Projects/<project> $ manage.py test dialog.DialogTest --failfast Creating test database for alias 'default'... E ====================================================================== ERROR: testPostDialogAnonymously (dialog.tests.DialogTest)

I'm not sure how to troubleshoot this further, please let me know what you need from me and I'll fix it.

    I can add that I don't have Johnny enabled when running my tests, since CACHES is not set at all, but the middleware classes are set. Could that be the problem here?

    UPDATE: no, the same error and stacktrace occurs if I set CACHES in my test settings file.
