I have a similar problem - does kdeinit4 take 100% CPU after it crashes? It does on my machine, and disables custom shortcuts as well. The process needs to receive a SIGKILL, SIGTERM won't do the trick. Shortcuts aren't functional until you do a logout/re-login or reboot the system.

Status changed to 'Confirmed' because the bug affects multiple users.
