I'm getting the same thing, on an old Dell Inspiron 8200.
Video card is an nVidia GeForce4 440 Go, using the 96.43.17 driver.
I also tried the 96.43.16 driver with the same results.

One strange thing that I found was that using gdm for a  display manager, the problem goes away.
With gdm, I can log out, and still have a working system with terminals, and it will log back in OK.
Using either kdm or xdm, I have nothing but black screens after logging out.

When I ssh into the computer (after logging out of KDE), top shows 99% cpu for Xorg.
If I kill the process, then the login screen returns, and I can log back in to KDE.

Here's the result of tail -f /var/log/Xorg.0.log as I am logging out of
KDE:
