If someone uses SessionMiddlware, any request with invalid cookies will result in a stack trace. For instance, someone visited a site with the cookie
If one were to use wget, you can repeat this on a number of sites:
$ wget --header "Cookie: lang:xml=ru" http://www.djangoprojects.com --09:06:39-- http://www.djangoproject.com/ => `-' Resolving www.djangoproject.com... 22.214.171.124 Connecting to www.djangoproject.com|126.96.36.199|:80... connected. HTTP request sent, awaiting response... 500 Internal Server Error 09:06:40 ERROR 500: Internal Server Error.
(It's also amazing how many Django developers are lazy enough to leave PythonDebug on, but that's not fixable.)
Attached is a patch to have invalid cookies result in no cookies at all, along with a test.
Someone might decide to emit a warning or something, that's not included in this patch.
