Controller Specs Using 2-Legged OAuth fails

[coneybeare]

I can make a request via rails console fine, so I know the app has been implemented correctly. When using the provided helper methods to sign the simple get request in the controller spec, the request does not appear to be signed correctly. Am I doing something wrong?

The successful console call:

coneybeare $ rails c test
Loading test environment (Rails 3.2.0)
rails test: main 
>> consumer = OAuth::Consumer.new("one_key", "MyString", :site => [REDACTED])
# => #<OAuth::Consumer:0x007f9d01252268 @key="one_key", @secret="MyString", @options={:signature_method=>"HMAC-SHA1", :request_token_path=>"/oauth/request_token", :authorize_path=>"/oauth/authorize", :access_token_path=>"/oauth/access_token", :proxy=>nil, :scheme=>:header, :http_method=>:post, :oauth_version=>"1.0", :site=>[REDACTED]}>  

ruby: main 
>> req = consumer.create_signed_request(:get, "/api/v1/users.json", nil)
# => #<Net::HTTP::Get GET>  

ruby: main 
>> res = Net::HTTP.start([REDACTED]) {|http| http.request(req) }
# => #<Net::HTTPOK 200 OK readbody=true>  

ruby: main 
>> puts res.body
{"users":[{"id":206669143},{"id":358143215}]}
# => nil  

The failed controller test:

    it "responds as success with a valid oath signature" do
      consumer = OAuth::Consumer.new("one_key", "MyString", :site => [REDACTED])
      two_legged_sign_request_with_oauth(consumer)
      get :index, {:api_version => 'v1', :format => :json}
      response.should be_success
    end

coneybeare $ rspec spec/controllers/client_applications_controller_spec.rb --fail-fast; echo "==================================="; tail -6 log/test.log 

  1) Api::ClientApplicationsController GET index responds as success with a valid oath signature

My versions are:

coneybeare $ bundle show oath
/path/redacted/gems/oauth-0.4.5
coneybeare $ bundle show oauth-plugin
/path/redacted/gems/oauth-plugin-0.4.0.rc2

Is this a bug? If not, can anybody point me in the right direction for testing controllers that are oauthenticated with a 2-legged approach?

There is a SO question about this with a bounty... any help is much appreciated. I just want to run my controller tests :/
