The forum has been too quiet regarding Defcon for this year.  Time for a meetup thread..
Like last year, I'll grab a table in the chillout room.  I haven't decided what the best day or time is, so I'm open to suggestions.  Chatting all things Bitcoin [and more] at the hacker-con was a blast last year.  Bitcoins were exchanged for bar-runs, donations were made to the Defcon kids Bitcoin challenge, and more-- so bring your mobile wallet.

Unlike last year, Pirate won't tell everyone he is going and no-show.  And if for some weird reason Pirate shows this year- you can give him a piece of your mind instead of all your BTC

Discuss........

I have a 52 character private key (starts with 'L').  The wallet.dat was encrypted some time after the block was solved, and became corrupted to the point that the bitcoin.org client would not open with it.  I extracted the keys with pywallet and managed to import and spend all of the block rewards in the wallet except this one.

Here is what is interesting:
1) I can NOT import the key into an unencrypted wallet with pywallet.
2) I can import the key into an encrypted wallet with pywallet, and the balance is shown.
3) If I attempt to send all or part of that amount, the client reports "Transaction creation failed".
4) Nothing shows up in the debug log.
5) I can import the key to a blockchain wallet and the balance is shown (still cannot send).

Is pywallet able to handle 52 character keys correctly?  
Any ideas why this works with encrypted wallets only?
