Summary: NPE in Mo.calcXScaleFactor

Initial Comment:
If I call JMathComponent with a very simple MathML fragment containing a sum operator, a NullPointerException happens.

This produces the exception: <mrow><mo>&#x2211;</mo></mrow>
This works: <math><mrow><mo>&#x2211;</mo></mrow></math>
This works: <mrow><mo>&#x2211;</mo><mi>x</mi></mrow>

The attached test case produces the exception.
