The operator created to download from quay the catalog of our bundle reports that the catalog was not loaded

and the status mentions

reason: Error
          message: >
            time="2019-08-28T13:48:09Z" level=fatal msg="error loading manifest
            from remote registry - strconv.ParseInt: parsing \"v0\": invalid
            syntax" port=50051 type=appregistry

It should then great that such error is checked by operator-courier verify step.
