"Errors" constantly being spammed into output (1317 errors!)

See summary. I can't think of a good way to reproduce this bug. What I do know for sure is that this didn't happen in previous snapshots. It might have something to do with dying via walking inside berry bushes, as I died this way, and all these errors happened while I respawned.

If I am asked to provide the whole game log, I don't think that would be possible. Each error has more than 50 lines, even on 100 lines.
