Hi. This seems like the data is corrupt (possibly unclean shutdown?).
Please try restoring from a recent snapshot / backup or full sync.

Hi, have found a second user with exactly the same problem. For him, the problem occurs every time he activates pruning. This is reproducible. In my case, pruning is also activated. Perhaps you can check whether activated pruning also leads to this error in your test lab. (In the meantime I have updated to V.4.0.4 - same problem)
