[ghost]

django_nose is installed, TEST_RUNNER is set to 'django_nose.NoseTestSuiteRunner', NOSE_ARGS is set to ['--with-coverage', '--cover-package=relog_core',].

Running python manage.py test results in the following tracebacks:

AttributeError: type object '_TestState' has no attribute 'saved_data'

I'm not calling setup_test_environment or teardown_test_environment anywhere in my tests, and I don't get this error when running without nose.
