Pulp

To reproduce use any plugin with metadata, e.g. RPM plugin:

1. https://pulp-rpm.readthedocs.io/en/latest/workflows/create_sync_publish.html
2. Try to get any repodata: http://localhost:8080/pulp/content/foo/repodata/repomd.xml nad get 500 Internal Server Error
3. For content with artifacts (packages), it works fine: http://localhost:8080/pulp/content/foo/bear-4.1-1.noarch.rpm

It should also be reproducible with pulp_file and attempt to get PULP_MANIFEST.
