So I had a balance of 2 bitcoins that I took out from a pool.
Sent to my address via hash key.

Balance was 2.06943 whatever the # was.

I sent 2 coins to MT GOX, but the bitcoin.exe client froze/locked up and it was stuck on the send screen where you accept the fees.
I closed bitcoin, re-opened it. I sent my 2 bitcoins to MT GOX and it went through.

Right after the 2nd try, I see two of the same amounts to MT GOX both -2.01 to the same address.

One says 6/comfirmed which is good, other says 0/offline? which I'm hoping it caught the mistake and invalidated it.
However, now the 0/offline is back at 0/uncomfirmed, how do I get rid of that one? I think the system took a crap on me for my mistake.

Thanks.

It sounds to me like it did a double spend attempt.  The first one spend probably went through eventually, after it was included in a block.  Thus what you are seeing is your second attempt stuck at 0/unconfirmed.  It will never confirm because it has already been spent.

[Upate: I'm not sure how that database wouldn't know that the first transaction had been made.  Perhaps the database rolled back the transaction when it recovered after the crash?]

I don't think there is anything you can do about it other than send any coin balance to a new wallet and toss [Update: "archive" never toss, in case you receive payments to it] the old one.  (though once merge wallet is available that would be an option too: http://forum.bitcoin.org/index.php?topic=8091.0 ).

I may be wrong on all this, but from the info you provided this sounds plausible.

You should check block explorer also.  I would bet the unconfirmed spend was not included in any block there either.

This might help you:

Thanks guys, it was a double spend as the application froze =\.

Appreciate it!
