Crashing QT Wallet 2.2.0 about pivx HOT 9 CLOSED

Are you using a backup "wallet.dat" file, or are you creating a new one? Because I had problems with a corrupt "wallet.dat" file, so I had to generate a new one. Now my wallet is stable.

from pivx.

It's the same wallet i used for 2.1.7 that wallet crashed as well. Was fresh then. The older qt version branded pivx wallets all crashed as well so it's not a corrupt wallet.dat. presstab mentioned something about a memory leak in the qt wallet.

from pivx.

For this helped:

1. remove ~/.pivx folder(Backup wallet.dat)
2. start pivx-qt
3. wait for the wallet to download the whole blockchain
4. when syncing is done, exit wallet, add the backup wallet.dat to ~/.pivx
5. start pivx-qt

Crashed again. Nothing in any logs this time. Don't know how to make it show more info for Devs to see what prob is. I using Daemon for masternodes and they are ok so far. Qt wallet is unstable for staking ATM.

seeing these in log. the last bit was just at the crash.

from pivx.

This is likely due to the Trading Dialog... which runs in the background. We are disabling it as it has caused many problems. There are few other things in the code that use QIODevice. Thanks for posting this, very helpful.

I got the same crash, and I just checked the debug.log there is no info on the crash. I checked the db.log and it's empty.

I have backed up the corrupt blockchain if you want to use let me know

@lekanovic please try building from #146 and letting me know if this takes care of the crash.

@borris345 confirmed that the wallet is no longer crashing with the latest commits.
