ksmserver crashed with SIGSEGV in start_thread()

[Rob A]

Binary package hint: kdebase-workspace

I just hit "CTRL-ALT-F1" to go to the console, and the whole KDE system crashed and sent me to a logon screen. When I hit ctrl-alt-F1 again, I got a have-redraw of my previous session, and no ability to do anything in the GUI, or change to any consoles, so I ahd to reboot.
