Phew - Well I've found the problem. If you use SetFixedRotation(True) with a Prismatic Joint it crashes. Its does the same in the examples.
Thing is you don't need to fix the rotation (I just assumed you did need to), since bodys attached to this type of joint do not rotate anyway. Although I don't know why it would crash on the new version and not the old one, maybe there's been some slight changes.
BTW what does Warmstarting and Validate(), and Position Correction do? - it doesn't explain them in the docs. Just a brief explanation would be helpful.
Thank you - Rico
