It is not your wallet. The hash you supplied is for a different public key. I know because I have the wallet.dat too
It is obviously one of those "fake" wallet.dat's which has been modified to include public keys containing tens/hundreds of BTC and then sold for 0.1 BTC.

I'd like to point out that the OP actually did
put it up for sale in their CryptoTalk thread (via the pay2download file hosting service satoshidisk.com)
NOTE: DO NOT PAY TO DOWNLOAD THIS FILE!You'll most likely find that the password supplied will not allow spending of the BTCs... the private keys will be "encoded" in the wallet.dat file using some bogus data which makes it impossible to decrypt.
