Ubuntu 10.04 Lucid AMD64, Nvidia video driver, NVIDIA GeForce4 MX 440 AGP 8x

This has happened a few times:
User1 on F8 console
User2 on F9 console
 User2 playing streamed music in Firefox
 Switch to User1 on F8
   Music stops playing
   After around 30 sec:
                       Screen blanks
                       Drum roll
                       Login screen, on F9
                       The previous X session on F9 has crashed out, all the work on open windows gone.
I found the following log messages, but ultimately perhaps it is Xorg or nvidia that should take responsibility for the X session crash?
