rspec users - Nov 2010 - Problem testing Authlogic UserSession

I''ve posted this to the Authlogic group but things seem a little quiet,
so
perhaps someone here can help:

''m testing Authlogic 2.1.6, running under Rails 3.0.1., using rspec
2.1.0

I have the following:
user.rb
class User < ActiveRecord::Base
  acts_as_authentic do |config|
    config.login_field :email
    config.ignore_blank_passwords false
    config.disable_perishable_token_maintenance true
  end
end

user_session.rb
class UserSession < Authlogic::Session::Base
end

user_sessions_controller_spec.rb
require ''spec_helper''

def user_session_create
  @user = Factory.create(:user)
  @user_session = UserSession.create(:email => @user.email, :password =>
@user.password)
end

describe UserSessionsController do
  before(:each) do
    :activate_authlogic
  end

  describe "create a user session" do
    it "creates a user session using the user credentials" do
      user_session_create
      @user_session.email.should == @user.email
    end
  end

  describe "find a user session" do
    it "locates the user session" do
      user_session_create
      us = UserSession.find
      us.email.should == @user.email
    end
  end
end

I have the correct lines in spec_helper.rb ( require
"authlogic/test_case"
and include Authlogic::TestCase)
The create a user session test is ok but the find a user session test is
failing with
Failures:
  1) UserSessionsController find a user session locates the user session
     Failure/Error: us.email.should == @user.email
     expected: "ron2.weasley2 at hogworts.com",
          got: nil (using ==)

When I try this using console, I get the following
ruby-1.8.7-p302 > require "authlogic/test_case"
 => true
ruby-1.8.7-p302 > include Authlogic::TestCase
 => Object

I''m at a bit of a loss to explain this - any help very welcome!
