Since Django 1.5.5, CSRF tokens are rotated on login. That makes it trivial to trigger a CSRF error in the following way:

1. Open your app's login page in two different browser tabs.
2. Log in using tab 1
3. Log in using tab 2

The CSRF token sent along with the second login attempt (in a cookie) won't match the token that was embedded in the form, and so a CSRF error will be displayed.

It could be argued that the above is an odd/contrived thing to do, and so displaying a CSRF error here isn't too bad. Fine. But there's another, more subtle, way to trigger the same thing:

The request could not be understood by the server due to malformed syntax. The client SHOULD NOT repeat the request without modifications.
