Strange webots behaviour

Hi, I've just downloaded webots 4.0.19 and the robot controller's
commands do not seem to be executing properly.  If I set joint 0 or 1
("back_1" and "back_2") to a small angle (15 degrees or greater), the
torso suddenly flips between the robot's legs, as if the angle changed
to around 180 degrees.  Anything less than 15 degrees works fine.

Is this a bug in the new judo.wbt file?  It didn't happen in 4.0.18. 
Does anyone else have the same problem, or know a way round it?
