active_support/whiny_nil.rb:52:in `method_missing' error occurs when I upgrade my rails 2.3.3 project to 2.3.17

Our rails project version is 2.3.3. Recently, however, we decided to upgrade rails version to 2.3.17 to patch the security holes.

But after upgrade my rails gem, I got the following error. Is there anyone whoh had a same problem?

And the ruby-1.8.7-p370/gems/rails-2.3.17/lib/initializer.rb:445's code is

ActionController::Base.session_store.name == 'ActiveRecord::SessionStore'
