I'm having private key issues.  I dumped some devcoins on a cold bitcoin address expecting to import the key into the devcoin client at a later date. Unfortunately it wasn't what I expected.

--For demonstration purposes on a throw-away address--

Using joric's pywallet with password on encrypted wallet, or rpc on both encrypted and unencrypted wallets I get:

        {
            "addr": "13E4sDkWHMBJqFe9yFWM1JyBmJz5LZKUEL",
            "label": "p2pmining",
            "sec": "L5iyipTyQ6kHHcumG2ihbBnqJFGBq9nXY53Mmp3uPBg5FE82vNTC"
        },

   

with jackjack's pywallet on unencrypted backup
 
       {
            "addr": "13E4sDkWHMBJqFe9yFWM1JyBmJz5LZKUEL",
            "hexsec": "c17449119f6cc1857f07d3cb53868b8df79b20d8c5a282d88ae19cb7d67ceba0",
            "label": "p2pmining",
            "sec": "5KHV7MizuJ9FXfoK1jongbYeAHiDL49FAQphAyoUgJ8jUrJi56i"
        },

when entering jackjack's keys in pywallet or bitcoin address utility, sec and hexsec match but return 1GHBZWaFFMfRh7AebRagZzkB7McaCZ5DPs as address instead of the 13E4sDkWHMBJqFe9yFWM1JyBmJz5LZKUEL address.  The key from the other methods only gets error messages.  I've imported keys from vanitygen before and everything was fine.  What am I doing wrong?
