Reason: There's a reputation multiplier for delegated votes, it's set to 0.8. Unfortunately, that rounds to 0, and we're not allowed to add 0 reputation.
So when we check whether or not a user has already voted, we try to enter 0.8 reputation to their rep, and this rounds to 0, and then there's a check that does not allow adding 0 to reputation (which is good - it showed us this error in this case).
Suggested fix: Add minimum 1 rep for adding into the votes table.
