I have found an old wallet.dat and I resumed it. I was convinced that there was several incoming transactions and only one outgoing transaction in this wallet.dat.
But the bitcoin-qt shows only the incoming transactions, and all the balance is available.
Well, when I try to spend my balance, of course, it remains pending and is never mined in the blockchain.
It doesn't even fit into the mempool.
Does anyone think it is possible to inform some of the developers to let them know this bug?
