I added a little script tools/zeitgeist-integrity-checker.py that allows us to debug for DB errors .
The solution that I would suggest for now is:
1. Allow the query to continue and return the healthy events and ignore the broken ones instead of just failing.
2. Look into how the broken events get in.
