I was playing SatoshiDice a bit earlier - one of the bets didn't get a response for a while, and when the response finally came through, it shows as a double spend...
My bet: 02686699327f1fc47c9f77f21fd1dab0abdf2775fca3101264caddd97ab79e62 has had several confirmations, but the response 569300ffd2866072a710754de6b0706330656dce17645cf1784d873285a661ac is unconfirmed, and shows as a double-spend of one of the coins building the transaction (not mine!).
[Edit: copy-pasted wrong transaction in initial post - now corrected]
How can this be resolved?
Edit: hmmm... looking at
https://blockchain.info/double-spends it seems that SatoshiDice is double-spending like crazy today ... so whoever's responsible for it is going to have a big mess to clear up somehow?
