It seems that sometines cleanup happens too early. To my knowledge, resources are cleaned after each test method. My guess is that the problem is that all resources and cleanups are introduced in the setUp. And then both test methods re-use the created resources. It seems that cleanup happens either too soon or just for the second time.

It's the only test class written that way. https://github.com/pulp/pulp_rpm/blob/ddb279b1dfba727a548e360388fedcc0e63732bd/pulp_rpm/tests/functional/content_handler/test_config_repo.py#L42-L57

Any other tests we have don't create resources or schedule cleanups in the setUp, everything happens in each test method.
