Comment 5 for bug 1518431

I've debugged this issue a bit further and it's not related to RadosGW. The swift driver deletes that last 0-byte chunk when the image is being uploaded and that's causing this conflict.

---
                    if bytes_read == 0:
                        # Delete the last chunk, because it's of zero size.
                        # This will happen if size == 0.
                        LOG.debug("Deleting final zero-length chunk")
                        connection.delete_object(location.container,
                                                 chunk_name)
                        break

                    chunk_id += 1
                    combined_chunks_size += bytes_read
