I get errors in ruby files using the double star operator (**)

def test(**options)
  p options
end
test(a: 1)
1 file inspected, no offences detected

2 errors occurred:
An error occurred while ShadowingOuterLocalVariable cop was inspecting test.rb.
An error occurred while UnusedLocalVariable cop was inspecting test.rb.
Errors are usually caused by RuboCop bugs.
Please, report your problems to RuboCop's issue tracker.
Mention the following information in the issue report:
0.9.0 (using Parser 2.0.0.beta9, running on ruby 2.0.0 x86_64-darwin12.4.0)

Debug output:

An error occurred while ShadowingOuterLocalVariable cop was inspecting  /path/to/test.rb.
