Updated to Bitcoin-QT 0.8.1beta. When loading the program I get the error "wallet.dat corrupt, salvage failed". Where do you start troubleshooting? I have tried recovering from a backup (`scp me@server:path/to/my/backup/of/wallet.dat ~/Library/Application\ Support/Bitcoin`), but still get the error. I've removed everything in ~/Library/Application Support/Bitcoin except for the wallet.dat (recovered from backup) and reran the client, to no help.

Extremely thankful for any help in troubleshooting this.
