24ae4b291cThe temporary URL key used for the download, before the real key is generated, was blocked by annex.securehashesonly. Fixed by passing the Backend that will be used for the final key into runTransfer. When a Backend is provided, have preCheckSecureHashes check that, rather than the key being transferred.
