I think it is a general QT/KDE BUG!
All QT/KDE apps (especially kdeinit) are linked against libGL/libGLU and not 
ONLY the apps which are 3D OpenGL accelerated.

Example:
kdeinit   15040 nuetzel  cwd    DIR        8,6    2864       176 /home/nuetzel
kdeinit   15040 nuetzel  rtd    DIR        8,3     592         2 /
