Public bug reported:

In token/provider.py, the following triggers an exception if revoke_api
is not loaded

        if self.revoke_api is not None:
            ....


The fix is to set self.revoke_api to None in the init:

    def __init__(self):
        super(Manager, self).__init__(self.get_token_provider())
        self.revoke_api = None


To recreate this, run the test_auth.py unit test:
nosetests test_auth.py
