Changing the PySequence_SetItem to PyList_SetItem and dropping the DECREF works for me too (PyList functions steal a reference). I also tried setting the list to length 1, still no dice. The PySequence version segs under 2.4 and 2.5. It segs even when the Int is changed to a String. Yikes, I'll poke around some more. -Jack -- http://mail.python.org/mailman/listinfo/python-list
