Steps to reproduce:
- Log in to the site as a regular (non-staff) user.
- Without logging out, log in to the admin area as a staff user.
- KeyError is raised by the application.
With reference to django/trunk/django/contrib/admin/sites.py, the login call on line 274 has the side effect of flushing/clearing out the session of the previously logged in user (as of ). This empty session causes the
delete_test_cookie call on line 277 to fail with a KeyError.
I think that the test cookie should only be deleted after checking
request.session.test_cookie_worked(). Note that there is
test_cookie_worked() call at line 244 but that does not account for the above case where the session is subsequently going to be cleared out.
