Error in generating Collision checking matrix - moveit setup assistant

edit

I am trying to configure moveit for ardrone robot model, 'quadrotor.urdf.xacro' provided with 'tum_simulator' package ( http://wiki.ros.org/tum_simulator ). When I try to generate collision checking matrix with ' moveit setup assistant', I get the following error,

terminate called after throwing an instance of 'boost::exception_detail::clone_impl<boost::exception_detail::error_info_injector<std::domain_error> >' what(): Error in function boost::math::binomial_coefficient<d>(unsigned, unsigned): The binomial coefficient is undefined for k > n, but got k = 2.

I have successfully configured moveit for some robots but in this case I receive this error. What is the reason for this error? Using a xacro or a urdf file, both throws the same error.
