It is as otether said, blockchain.info is not the best and trustworthy info about every bitcoin transaction.
There were some upsets lately with Satoshi's coins suddeny moving and it turned out to be blockchain.info bug as well.
The best course of action will be to wait day or two and see if this transaction will be confirmed.
Would you recommend another site in place of blockchain.info? I would like to have a trustworthy one.
