The new Stage3 world format is a little bit different from Stage2 one. The problem is that Stage3 segfaults if reading a Stage2 world, the problem being the pose and size tuples, that have an expected z coordinate, that Stage2 worlds do not have.

Isn't it better to display a message, e.g., "tuple lacking a value", instead of segfaulting?
