I recently deleted my mincoin folder and re-synced with the network as it was acting funny as far as syncing.
After mining on the new folder (new wallet.dat) I found a block, it shows as a transaction on the wallet but not as unconfirmed or confirmed balance they both show 0. Also there is nothing showing in the transactions. The log file shows:
