Test failing

[amo13]

When doing a runtests.py I get a failure, because apparently the secret key for django is empty.

  warnings.warn(

It seems to be looking for a secret key in the config file from the django package itself, but the secret keys for my application are stored in application specific config files elsewhere...

I'd like to suggest a fix in the test rather than ignoring it or working around it, but I am not sure how, I don't know python well enough.
