Also, it no only happen to that model, appears in any model, i get a feeling in how to reproduce it: 1. Put your app in apache wsgi (i have it in webfaction) 1. Try to enter a url who points to a view that have @login_required (Here the normal behavior is to redirect the user to login page, but sometimes, does not redirect, instead email me the error message*) 1. When redirected to login page, you login, and then works as normally Maybe its something when validating if the user is logged in for first time, but i dont have any idea, this is like the 20 error message that i get, so i consider it important.
