Just for fun - try putting it in a view specs instead and include the helper:
describe "FooHelper", :type => :view do
It might be that view specs have services you need for this example
that don't exist in helper specs. If it works, then you can use that
as a workaround for now and we know where the deficiency lies. If so,
please submit a ticket at http://rspec.lighthouseapp.com/.
