That's a very well, objective observation!
Hm, I can hardly remember having done anything special.
I had already successfully compiled 3.0rc3 on this machine (Well, 
successfully... with that release, Kicker died on startup on my machine, but 
at least KDE started at all.)

You mean  those programs under qt/examples/? Yes, they all work (at least 
those which were compiled by default), there are only some slight problems 
with some of the 3D stuff, but I don't think that matters here.

I have re-downloaded kdelibs and kdebase out of CVS today and recompiled them 
with debug on. The backtraces of the crashed programs now look like this:

------------------------------------------

I must admit I don't know very well how to read this output, but, say, 
doesn't that look a bit like the error resided in glibc?
