Client throwing error due to insufficient arguments check

[derwaldgeist]

I had a 3rd party library throw an error, which I could traceroute back to the event listener hooks of zone.js in meteorhacks:zones.

This line is failing:
https://github.com/meteorhacks/zones/blob/master/assets/zone.js#L947

The reason is that arguments[1] is null, which is not checked. So I get the error message that property _bound cannot be found in undefined.

Here's a screenshot of the failure situation:
