I have typed at the old PC(which was bought for the BTC-thing only. I known it would be big)
listaddressgroupings.
Using this: 2013-03-18 - Bitcoin-Qt version 0.8.1 released
It seems I shutted down the PC before the transaction of 7.35BTC was confirmed and at this time I have backed up the wallet. And already does a transaction 07.07.2013 which was never done from an address which is unknown for me in the addresspool too. This transaction was done while the transaction of 7.35BTC was unconfirmed too. This address holds the difference of the 1mAo and this "never done" transaction (6.945BTC).
blockchain.info says ther never was something at the address where
listaddressgroupings says there were/are 6.945BTC. It´s a dead address. No incoming, no outgoing.
The transaction you can see of 0.05 BTC which shortly was done, was done from an earlier backup of this wallet at a time where 1mAo not existed. The latest backup of this wallet contains 1mAo by checking
listaddressgroupings.
1mAo EXISTS!!!
But it has a zerobalance.
What´s to do? Just connect? It´s a small HDD (80GB)
I´ll tip you for sure
UPDATE: At the PC where is now running the latest version of bitcoin core and updating the chain the transaction of 7.35BTC is confirmed and the address which holds 6.945BTC without updating the chain has a zerobalance. But 1mAo too. The chain is not synced right now.
