Since a lot of people have been asking I though I would post this here to try and help people understand.

Any wallet is susceptible to the current BTC network problem. What happens is a transaction is broadcast to the BTC network. A malicious node then takes that transaction and mutates the data then broadcasts the bad information back out onto the network. When your wallet sees that transaction (because the id the wallet uses remains in tact) it thinks it sent the transaction (double spend). However because the data in the transaction is bad it will never confirm and the wallet will get stuck waiting for it. This is a problem for exchanges because all transactions both in and out get blocked by the wallet as it is waiting for the bad transaction to confirm (it never will). Many people have been affected by this as of late not just exchanges. The wallet.dat file must be edited and the bad data pulled out and the wallet is fine after that (did it twice yesterday). Regular users will either be stuck with a corrupt wallet or have to wait a few days for the bad data to be kicked out by there wallet.

In the paper that MTGox wrote the id they are talking about is the txid of the transaction broadcast on the network. There proposed solution is for the wallet (everyones) to stop using just the txid and to also use a secondary hash of the transaction. This way when a bad transaction comes to the wallet the wallet will reject it as the txid may match but the private hash doesn't so the wallet knows that the transaction has been tampered with.
