getBBox() missing values on text elements

I have a Node.js project which uses jsdom and Raphael Js to generate SVG markup on my server, all was going well until I started to get missing values when calling getBBox() on Raphael text elements.

var paper = window.Raphael(10, 50, 320, 200);
var txt = paper.text(10, 10, 'hello world!');       
console.log( txt.getBBox().toString() ); // Returns: NaN NaN NaN × NaN

whereas ...

var rect = paper.rect(10, 10, 10, 10);
console.log( rect.getBBox().toString() ); // Returns: 10 10 10 × 10

What would be the cause of this and more importantly is there a fix?

TextElement.getBBox() only work in browsers, it should not be used in server side.

You should use the print() method of RaphaelJs, which produces an array of paths. You can use getBBox() on the array to get the bounding box.
