If this output really comes from "PyObject_CallMethod", then some passed in argument is likely "null" - maybe "myclass"? The Python-C interface is complicated. It might be advicible to use e.g. "cython" to get the boilder plate code and some intricacies taken care of. I have done this with "dm.xmlsec.binding". You can find in its source also an example for the callback defined in Python and called from "C". -- https://mail.python.org/mailman/listinfo/python-list
