Comment 5 for bug 1494327

I'm able to recreate this consistently:

$ echo "keystonemiddleware.tests.unit.auth_token.test_auth_token_middleware.GeneralAuthTokenMiddlewareTest.test_auth_region_name" > my-list
$ echo "keystonemiddleware.tests.unit.auth_token.test_user_auth_plugin.V2UserPluginTests.test_user_information" >> my-list
$ .tox/py27/bin/python -m testtools.run discover --load-list my-list

These aren't the only 2 tests that will cause the 2nd test to fail. Could also use keystonemiddleware.tests.unit.auth_token.test_auth_token_middleware.GeneralAuthTokenMiddlewareTest.test_auth_region_name . I think it's actually any test that creates and AuthProtocol.
