This is FUD. Someone is trying really hard to push the market down. MtGox has withdrawing limits, which means that the only way to exploit the malleability bug is to slowly drain the hot wallets, and MtGox would have to keep replenishing them from their cold vault; also assuming that MtGox's system would resend apparently failed transactions. This means that there's no way they wouldn't have noticed missing funds in their balances. No way someone could slowly steal 750K BTC, without anyone noticing. Just no way.
