[rspec-users] hash form of stub_chain returning nil for chains with shared first message

I'm new using rspec, so please forgive me if I'm barking up the wrong tree, but...

I'd expect this to pass (using rspec 2.5.1)

describe 'stub_chain' do
  it "returns expected value from two chains with hash" do
    subject = Object.new
    subject.stub_chain(:msg1, :msg2 => :first)
    subject.stub_chain(:msg1, :msg3 => :second)
    subject.msg1.msg2.should equal(:first)
    subject.msg1.msg3.should equal(:second)
  end
end  

But it doesn't - subject.msg1.msg3 returns nil

I think this is because in stub_chain (in rspec-mocks/lib/rspec/mocks/methods.rb, line 43) there is

 if matching_stub = __mock_proxy.__send__(:find_matching_method_stub, chain[0].to_sym)
    chain.shift
    matching_stub.invoke.stub_chain(*chain)
 else

ie blk isn't used in any way. Changing this to matching_stub.invoke.stub_chain(*chain, &blk) makes my example pass
Is this true or am I just misusing rspec?

Fred
