Array with null elements crashes program

[JonathanWilbur]

xml({ foo: null }) works fine, but xml({ bar: [ null, null ] }) causes the program to crash. I know it seems like an edge case, but I am converting a JSON document from a database query and some documents contain arrays with null elements.

Here is the stack trace:

events.js:160
throw er; // Unhandled 'error' event

i would assume this is an intended feature.
