I don't think that's a problem. That test is doing a finite difference approximation to the force, and the result is coming out just barely outside its tolerance. I should make it do a more accurate (symmetric difference) approximation instead.
Thanks so much for tracking down this bug. We'll try to get out an update that fixes the problem as quickly as possible, hopefully within the week.
