[MathDOM] MathDOM 0.8 won't start

[Mario C. <mar...@to...>]

Hello,
I have a problem after I just downloaded and installed MathDOM 0.8.

I tried to do:

from mathml.lmathdom import MathDOM

but it crashes with:

It seems to me related to these warning that I receive just before the
exception is thrown:

/usr/lib/python2.5/site-packages/mathdom-0.8-py2.5.egg/mathml/termparser.py:288:
SyntaxWarning: Cannot combine element of type <type 'NoneType'> with
ParserElement
  Suppress(CaselessKeyword('ELSE')) + p_arithmetic_exp +

  Suppress(CaselessKeyword('END'))

But I don't know how to move on... Any help is greatly appreciated

Thanks
