I can reproduce the problem with the following environment:
Windows XP Pro

(I tend to think it is a Django/Oracle combination problem, because I
can't reproduce the bug with MySQL or Postgres.)
I was walking through the tutorial, during which I installed the 'admin'
site. I went to http://127.0.0.1:8000/admin/ and logged in with user name
and password, and then hit the following error.

Comment:
(Fixed formatting.)
FWIW, this is not generally re-creatable. I've got Oracle 10g XE on a
Windows box with Python 2.5.2 and have no trouble using using the admin
interface with that setup. I suspect the problem may be some
configuration issue but I don't know enough about Oracle or
contrib.sessions to say what might be going wrong in your case.
