Hey idontknow,
It seems it's got something to do with a gamepad that's not fully plugged in (SDL detects it as a "null" gamepad, therefore the crash). What gamepad model is it? Could you try plugging it out and back in?
If that doesn't work, could you try starting the game without the gamepad plugged in and see if it runs fine? If it does, try plugging it in.
Thanks!
