Christian Heimes <[EMAIL PROTECTED]> added the comment:
The FileIO construct segfaults because PyArg_ParseTupleAndKeywords()
sets name to an invalid but non NULL value. PyMem_Free() tries to
deallocate name but fails.
Suggestion: Either appy this patch or change
PyArg_ParseTupleAndKeyword()'s behavior for 'e'.
