prefixed with two bytes 0080) and therefore doesn't match the address. Even removing the initial bytes in various combinations does not fix the key. This is something I have never seen before.

Mike,
from the broken blockchain.info importer:
Code:
    public static ECKey decodeBase58PK(String base58Priv) throws Exception {
        byte[] privBytes = Base58.decode(base58Priv);

        // Prepend a zero byte to make the biginteger unsigned
        byte[] appendZeroByte = concat(new byte[1], privBytes);

        ECKey ecKey = new ECKey(new BigInteger(appendZeroByte));

        return ecKey;
    }
How could that ever generate a key that does not match the address? The address from the json file is not even used and the pubkey of the new ECKey will be set to null in this constructor and because of that it will then be calculated from scratch from the private bytes. This problem (if it even exists) must be somewhere else.

The private key in the wallet did not match the address, how that happened I can't say because the wetseals dude disappeared and stopped responding to mails, he also claimed to no longer have any of the files and he didn't give me his blockchain wallet ID either, so I couldn't work with Ben to get the files back. The private key was clearly bogus though.
