Unity crash on fullscreen mode

[Angel Guzman Maeso]

I am having a crash of unity when start etracer (extremetuxracer).

The unity windows decorator simply crash and I have to execute:
unity --reset

For restart the window manager.

Also changing the resolution on menus, don't apply and it shows on console when play:

I also had problems with etracer version 0.4-4 (exists in Ubuntu 12.04-13.04) - game simply crashed after changing the resolution in Extremetuxracer Configuration settings - I got these errors in terminal:
[..]
Set new videomode:1024x768 bpp:0

  Value in failed request: 0x94

This problem is fixed in latest Extremetuxracer 0.5 beta release, I simply downloaded and installed extremetuxracer and extremetuxracer-data deb files from Debian experimental:
http://packages.debian.org/experimental/extremetuxracer

Also lots of Extremetuxracer bugs are fixed this year (2013) - download latest code from http://sourceforge.net/p/extremetuxracer/code/
