In one case I have to check the return value of PyObject_Call, and if its not of the correct return value, I throw an exception, but I just get a simple output:
TypeError: Expected an instance of XYZ, no int. instead of Traceback (most called...) TypeError: in line 3, file test.py: expected an instance of XYZ, no int... -- http://mail.python.org/mailman/listinfo/python-list
