I already checked the Autostart folder, xinitrc, and removed everything in ~/kde/share/config/session. None of that fixed it.
The user accidentally removed everything in ~/kde/share/config/ which worked, but wiped out ALL of his configurations, email, desktop, mail filters, Konqueror, etc, etc, etc. He even got the first run wizard. Not the correct solution by any means, but he's back into KDE.
I've tried recreating the problem, and have been totally unable to do so. As far as I can tell right now, this was a fluke, not a bug.
