It sounds like the operation's internal code failed or, possibly, that the operation was cancelled. Check the value of [op isCancelled] and [op isFinished]. If it's finished and not cancelled, then it ran to completion and the problem has nothing to do with the operation queue. I don't have any idea why it might have failed. That would be a matter of the implementation of QCCAESPadCryptor and/or the specific cypher text, key, and input data you're passing it.
