Segmentation fault if all weights are set to 0

[j03m]

Run this code:

var HashRing = require('hash_ring');
var obj = {};
obj["A"] = 0;
obj["B"] = 0;
obj["C"] = 0;
var ring = new HashRing(obj);
var instance = ring.getNode("hi to the world");
console.log(instance);

The result will be:

node hashRingTest.js
Segmentation fault

Easily rectified by changing all of the "0"'s to "1"'s but tough to determine the cause. Figured I'd post.
