Only fail if there were any keys in the backup (which does mean that the backup will always succeed if there aren't any keys which could also be misleading, but is probably not as bad and can probably be fixed with Trust on Decrypt). Also cheekily fix the error message so it talks about passphrases if you used a passphrase and recovery keys if you used a recovery key.
