In an attempt to support the BitGold - initiative I tried the following steps on my WIN7/64  / v0.5.3 wallet:

Short:
Transaction #d0bda0eb

Block #1695271, Prev #1 , Transaction #2 , Next #0
TimeStamp: 02/03/2015 7:51 PM

{"type":"short_op_v2_type","data":{"amount":2417555275,"short_index":{"order_price":{"ratio":"0.","quote_asset_id":7,"base_asset_id":0},"owner":"BTSJDgUSxoPgt2MprDVvpz5PpTbTkYqChRjY"},"limit_price":null}}

Buy short: Transaction #6a40a1cc

Block #1695295 , Transaction #0 , Next #0
TimeStamp: 02/03/2015 7:55 PM

{"type":"ask_op_type","data":{"amount":1208898516,"ask_index":{"order_price":{"ratio":"0.00008271993","quote_asset_id":7,"base_asset_id":0},"owner":"BTS7KQz7Lk7HmwktYHWnwmUmQBKRvesA6M3W"}}}
 Withdraw 1208908516 satoshi amount of asset

All went well and the balances showed up in the account, so I tried some bigger amount:
Transaction #2c6a4914

Block #1695804 , Transaction #0 , Next #0
TimeStamp: 02/03/2015 9:20 PM

{"type":"short_op_v2_type","data":{"amount":9848808160,"short_index":{"order_price":{"ratio":"0.","quote_asset_id":7,"base_asset_id":0},"owner":"BTSDnvBUXv2AEpkchCbs7mwJk5q5GecxyxgY"},"limit_price":null}}
 Withdraw 9848818160 satoshi amount of asset


The short showed up. Tried to buy back - whammm wallet_total_ freeze - 

After restart the wallet didn`t even know my PW.. so I had to rebuild the whole thing from scratch. Finally with an old copy of the wallet, chain download and some hours gone I had a fully operational wallet again. 

The transactions (see code) are here, the BitGold is "gone".  Tried:
 
- rescan
- wallet_regenerate_keys ACCOUNT-NAME 10500
- wallet_recover_transaction TXID

Thank you for some ideas for next steps to regain access to the purchased BitGold
