Unable to view dashboard - undefined method `zero?'

[ghost]

I've tried a hard reset on the Snorby database and it's still not working properly. It works when there are no events in the database. Once events get created it starts having this problem.

Looks like a sensor event_count is showing up as nil?

Weird, after re-naming the sensors the error has gone away. I did restart apache and passenger so, possibly a dirty or broken cache?
