Blender seg fault

I am running Kubuntu 7.04 and I installed Blender but every time I try to start the game engine, I get a segmentation fault. Actually, here is the output from the console:

guessing ‘blender-bin’ == ‘/usr/bin/blender-bin’
Compiled with Python version 2.5.1.
Checking for installed Python… got it!
Ignoring Xlib error: error code 169 request code 145
Ignoring Xlib error: error code 169 request code 145
Detected GL_ARB_texture_env_combine
Detected GL_ARB_texture_cube_map
Segmentation fault (core dumped)

The

Detected GL_ARB_texture_env_combine
Detected GL_ARB_texture_cube_map
Segmentation fault (core dumped)
is what is written after the game engine is started. Any idea how this came about and how I can fix it? It is the same with version 2.43 and 2.44.

The game forum may be better suited for this question. Search turned up the following:
