Comment:

 The same issue can be reproduced in newer versions. I've tested it in
 3.0.4 with database-backed sessions and all of the standard
 django.contrib.auth.urls
 Steps to reproduce:
 1. Open the first tab, login to your app.
 2. Open the second tab on "password_reset" page. Enter the email of a user
 from the first tab. Submit form.
 3. Click the "password_reset_confirm" link from an email that should've
 been received. Fill the form with your new password and submit it.

 This will trigger this line
 
[https://github.com/django/django/blob/master/django/contrib/auth/views.py#L302]
 against session without INTERNAL_RESET_SESSION_TOKEN which will lead to
 KeyError

 Way to fix the issue: use .pop() instead of del

 {{{
 self.request.session.pop(auth_views.INTERNAL_RESET_SESSION_TOKEN, None)
 }}}
