Yes. Thanks a lot, Dotan. I didn't know about this. Very useful indeed!

This still leaves the question how to log KDE activity. Actually, it looks as 
if this "freezing" has something to do with compositing being activated. KDE 
hasn't yet failed after compositing had been disabled.

Actually, doing research with composite effects added brings up the following, 
so it seems that I am not alone. Different to the report: I am using an intel 
945 GM chipset with driver "intel" activated in xorg.conf.
