Comment:
Thanks for this ticket, however we will not be able to reproduce this
issue with provided info. IMO it's not an issue in Django, but something
with you're configuration/environment. Maybe you're using Python that's
not supported by this version of Django, it's hard to tell. I think you
should try to use one of
[https://code.djangoproject.com/wiki/TicketClosingReasons/UseSupportChannels
support channels]. You can also try to provide a sample and small project
that we can use to reproduce this issue.
