Txindex cannot recover from ungraceful shutdown

[abrkn]

1. Run drivenet-qt
2. Stop it using kill -9
3. Start drivenet-qt
4. Receive message in GUI saying tx index has to be rebuilt
5. Press yes
6. Get message saying there is a corruption
7. drivenet-qt quits

Workaround: Delete blocks and chainstate folders before restarting drivenet-qt

It appears to be happening even when shutdown is done gracefully. Perhaps it's because I run with txindex=1? (Needed for the block explorer)
