I'm setting up a Django site that was transferred over to me and I've hit a strange error. This is only happening on the pages that call the template code below. I've tried removing the template call and the application just returns a 500 error. Has anyone ever seen something like this or possibly be able to suggest a method of further troubleshooting? Ubuntu12, Apache2, MySQL, Mod_Python, Python 2.7, Django 1.4
