[Answer]-Mod_wsgi 3.4 bug where 404 errors are misinterpreted

This probably is not a mod_wsgi bug.

Please make sure you have a 404.html file in your ‘templates’ folder. If Django cannot locate a template for the 404 error, it serves up an Internal 500 error.

Note: If this doesn’t solve the error, please take a look at this page on how to make a 404 error page work.
