Fix issue 2435

Apparently a bug was introduced in django_load.py. This code is not in sync with the source repo at: https://github.com/ojii/django-load where this issue has been fixed.

Ojii asked me (via IRC) to document this via this issue, and in my effort to clear out some of my old issues, I thought I'd simply post this fix. However, I suspect there's a deeper issue of why doesn't django-cms simply reference the source repo, instead of copy the code into the project?
