Problem with resources controller on destroy

[cpjobling]

Rails 2.3.2.

I created a new project. Installed the resources_controller plugin. Generated scaffold for a model:

ruby script\generate scoffold projects title:string description:text resources:text created_by:integer.

Edited projects_controller to remove rails generated scaffolding, and make it:

class ProjectsController < ApplicationController
resources_controller_for :projects
end

Then ran rake test

Functional test (generated by scaffold) fails on should_destroy.

Redirect should be to

test_should_destroy_project(ProjectsControllerTest):
Expected response to be a redirect to http://test.host/projects but was a redirect to http://test.host/projects.%23%3Cproject:0x54c11fc%3E.

It looks like a bug: .%23%3Cproject:0x54c11fc%3E is an object where an empty string was expected. But maybe I missed something in the configuration.

Routes file looks normal enough:

(in D:/InstantRails-2.0-win/rails_apps/test-rc)
projects GET /projects(.:format) {:controller=>"projects", :action=>"index"}
POST /projects(.:format) {:controller=>"projects", :action=>"create"}
new_project GET /projects/new(.:format) {:controller=>"projects", :action=>"new"}
edit_project GET /projects/:id/edit(.:format) {:controller=>"projects", :action=>"edit"}
project GET /projects/:id(.:format) {:controller=>"projects", :action=>"show"}
PUT /projects/:id(.:format) {:controller=>"projects", :action=>"update"}
DELETE /projects/:id(.:format) {:controller=>"projects", :action=>"destroy"}
/:controller/:action/:id
/:controller/:action/:id(.:format)
