Description of problem:
This is about an update installation of Skipjack beta2 over Enigma.
An old but updated KDE config file in $HOME/.kde/share/config causes the task
switcher (ALT+TAB) to lock the keyboard and KDE. Mouse cannot click anything
anymore. Keyboard is dead. CTRL+ALT+BACKSPACE doesn't work either. Didn't try to
log into the machine via network to see what would still be running. (Kernel is
still seen flushing the disk buffers periodically.) I've went through
$HOME/.kde/share/config in binary search fashion to remove every file that
doesn't affect this bug and find what the cause of this is.
Version-Release number of selected component (if applicable):
Steps to Reproduce: [see attached file]
1. rm -rf ~/.kde
2. tar xfz home.kde.tgz -C ~
3. log into KDE via kdm
4. have no windows/tasks active (!)
5. press ALT+TAB
Actual Results: _No_ "*** No Tasks ***" box is displayed. Further key presses
or mouse clicks lock the system.
Expected Results: A dialog box reading "*** No Tasks ***" should appear. KDE
should not lock.
Additional info: [If any window is open, the task switcher toggles through the
available windows, but without its selection box.]
It's ~/.kde/share/config/kwinrc that's is the problem. Removing it is a
work-around. But anyone with a similar kwinrc doing an update installation over
Enigma is likely to see this killer bug.

KDE config files for reproducing this bug
It didn't make any sense to change the "Product:" and "Version:" fields to Red
Hat Linux 9, since the original report was not about that product.
I smell that no one is going to take a shot at debugging or fixing this rare bug
anymore these days. ;)
Hence I close this as WONTFIX. If you disagree, reopen.
