initializing Types.base.JointsTrajectory with parameters fails

[renan028]

Fails:

traj = Types.base.JointsTrajectory.new(
                names: [],
                elements: states,
                times: dtimes)

Works:

traj = Types.base.JointsTrajectory.new(
                names: [])
traj.elements = states
traj.times = dtimes

undefined method `[]' for nil:NilClass (NoMethodError)
