For reasons explained by Steve, please send this instead to python-list
https://mail.python.org/mailman/listinfo/python-list
To access python-list as a newsgroup, skip comp.lang.python and use 
newsgroup gmane.comp.python.general at news.gmane.org.

I will respond there after testing/verifying and perhaps searching 
bugs.python.org for a similar issue.
