Strange behavior when exiting game

[phrippenatthekrotz <phrippenatthekrotz@iinet.net.au>]

Hi Maintainers,

I have Squeeze install, with both the gnome & kde desktops installed, 
using the kdm manager.

When I play gl-117 in kde,  the game plays fine until I quit the game, 
this is when the weirdness starts.  I quit,  then I am dropped to the 
gnome desktops background!  The mouse still works but nothing else.  I 
can not get the machine to do anything it is frozen with just the gnome 
desktop background displayed. I need to reboot to gain control again.

Is this a bug?  It is reproducible, happens every time,  however if I 
use gnome, the game quits normally and the desktop is useable.

I have limited knowledge as to how to track this behavior,  which logs 
to look at etc, I wonder if I have a strange bug or is this a known issue?

Hope you can help.

Regards Stan
