Happened again this morning. Evolution, Konquerer, Firefox and Konsole running. Did the same thing, switch to another session, killall xscreensaver, go back to session 7. When I get back to session 7, it restarts X. New information is that it is moving the mouse after the switch/killall/switch-back process that causes X to restart.
