Inspection incorrectly warns about number of arguments

I have a test like:

    it 'has a valid factory' do
      assert create(:widget).valid?
    end

The line with `create` is underlined in red.  Mousing over, it says: "Found 1 extra argument(s)".  The method actually being used is FactoryGirl.create, which accepts any number of arguments.

    def create(name, *traits_and_overrides, &block)

Now, it's not reasonable to expect the static analysis to know that I'm using FactoryGirl.create, as it is included at runtime:

    class ActiveSupport::TestCase
      include FactoryGirl::Syntax::Methods
    end

So, do I have to disable this inspection?  I'd rather not, as it's useful in most other situations, but I can't have every third line of my tests underlined in red.

I am using rubymine 6.3.3

Thanks!
