Comment 2 for bug 1457100

That is odd. I was able to get it to happen reliably yesterday while using a temporary virtual environment with only installing python-novaclient. Unfortunately I deactivated it and it was deleted.

However, under a slightly new scenario I can still get it to happen.

If I have an auth_plugin that registers itself via the openstack.client.auth_plugin entrypoint. The moment that ep.load() is called from novaclient.auth_plugin.discover_auth_systems I get the above message.

Even if the class that the entry point references does nothing such as:

class TestAuthPlugin(object):
    pass
