Package lists Red Hat, Inc as a vendor tag. This causes various problems. I've verified that the tag is not set in the spec, so a rebuild should fix it. Please bump release and rebuild for rawhide. I'd do this myself, but package ACL's are preventing me from committing. Also consider removing those.
Rebuild done, should be fine. If you're interested in pychecker commiting etc., do request here: https://admin.fedoraproject.org/pkgdb/packages/name/pychecker
