This is the code for the C++ class and the wrapping. I took out everything 
but a constructor, but I have the same problems. It's loaded because the 
Python object is using it right before I try to extract the object.

class MyPoint    {
     public:
         MyPoint() {}
};

BOOST_PYTHON_MODULE(JimsModule)
{
     class_<MyPoint>("MyPoint", init<>())
     ;
}

Nope...same result.

Thanks for your comments in the last email. 100 times simpler and cleaner 
now, and no I didn't need PyImport_AddModule in there. I'll put together a 
example of this problem and post it.
