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 support channels. You can also try to provide a sample and small project that we can use to reproduce this issue.
