I am not 100% sure if it's the bug you've mentioned, but there was an internal collision inside the hinge near the limit angles that caused some troubles. Smaller colliders will fix it.
However, there will always be external collisions (between other blocks connected to the joint) that could lead to unwanted reactions (disintegration).
