Traditional financial systems have established administrative body and practices, risk monitoring systems, fraud insurance and "slowness" that actually helps in cases as these (eg. You very often can undo transactions, by freezing funds somewhere across the world and then resolve those issues later on). Imo cases like these will be crucial in adoption of crypto currencies and smart contracts. And if there will be no (administrative) safe guards against cases like these, it might as well be the end for crypto currencies, simply because of lack of general trust in them.
