TypeError: Cannot set property 'parent' of null

If you try to walk the source of wysihtml5, detective will throw TypeError: Cannot set property 'parent' of null -- /node-detective/index.js:7:22
Here is a simple example that demonstrates the problem:
var detective = require('detective')
, request = require('request')
request('https://raw.github.com/xing/wysihtml5/master/dist/wysihtml5-0.4.0pre.js', function (err, response, src) {
console.dir(detective(src))
})
Here is the node it's looping over. I can't figure out what is causing the node to be null, but it looks like that comes from esprima or escodegen
[ null,
{ type: 'Literal', value: 0 },
parent: { type: 'ArrayExpression',
elements: [Circular],
parent:
{ type: 'LogicalExpression',
operator: '||',
left: [Object],
right: [Circular],
parent: [Object] } } ]
I found this issue when upgrading to browserify v2.

The null returned from esprima is caused by this [,0]. I'll throw together a test.
