nvidia driver crashes sauerbraten

I'm running gutsy with a nvidia geforce n6600 and the linux-restricted-modules 2.6.22.14.20

When I start the game sauerbraten it crashes immediately.
This happens with or without compiz running.
I've tested it and it works on feisty and on a gutsy machine with an ati card.
Glxgears works and so does google earth and other 3d programs I run.

When running it from the terminal i get the following:
