math formula breaks with empty nodes

[GoogleCodeExporter]

What steps will reproduce the problem?
1. an empty node causes it to fail.

What is the expected output? What do you see instead?
There is no output because the Class fails.

What version of the product are you using? On what operating system?
Latest.

Please provide any additional information below.
I have added the following line of code to the loadNode function in the 
MathML Class.  This gives some data so the procedure doesn't fail.

if(node.toString()==""){node.setChildren(" ")};

Here is the example equation I used that has an empty <mi> node in it.

<math><mrow><mi>w</mi><mo>&minus;</mo><mn>2</mn><mfrac><mrow><mn>1</mn></mr
ow><mrow><mn>2</mn></mrow></mfrac><mo>+</mo><mfrac><mrow><mn>2</mn></mrow><
mrow><mn>2</mn></mrow></mfrac><mi></mi><mo>=</mo><mn>2</mn><mfrac><mrow><mn
>1</mn></mrow><mrow><mn>3</mn></mrow></mfrac></mrow></math>

Thanks,
David
