NullPointerException when setting viewBox dynamically

Hi Thomas or Cameron,

I have a problem with the following file where I dynamically change the 
viewBox of the document.documentElement:

The file is at http://www.carto.net/neumann/temp/test.svg - one script 
file is linked.

After I set the viewBox I get the following error message:

java.lang.NullPointerException

Is this a bug in Batik or did I do something wrong in my code?

Thanks for any clarification and all the best,
Andreas
