Python Support

I would hesitate to say that this is an issue with the Python plugin, as in the past we've traced similar issues down to FedoraPeople hosting [0]. In any case it is an issue experienced first/only with the Python plugin.

The test fails intermittently. Run several times in succession locally, I had a few failures and a few successes, with no changes to the code or even restart to Pulp. The invalid checksum is consistent, it is the same every time it fails.
