That transaction will never confirm, the transaction funding it is not present and the balance of the bitcoin address is zero. Satoshidice sent you 0 confirmation coins that never confirmed and you spent them. You should remove all unconfirmed transactions from your wallet with
pywallet.py -web and then restart
bitcoin-qt -rescan to see if there is any balance restored to your wallet.
If you feel like gambling in the future, send money to the address in my signature and I'll bet you the same amount that you send that I won't send it back.
