This problem stems from wxPython using new-style classes and bad code 
on my part. I should have been using setattr instead, so change that 
line in model.py from:

self.__class__.__dict__[aMethod.__name__] = aMethod

to

setattr(self.__class__, aMethod.__name__, aMethod)

and addMethod should work again using wxPython 2.5.1.5 and PythonCard 
0.7.3.1.
