Public bug reported:
I tried "Guest Session", which worked fine, but returning to original
user, got this crash. Same thing twice in a row, so at least somewhat
repeatable. Using up-to-date (updated today) Lucid. Not sure if I should
be reporting this under gdm-guest-session or kernel, but for now
following apport's recommendation. It seems like a separate bug from any
others that exist as it's specific to using the guest session. Please
let me know if there's anything I can do to help with problem
determination and as always, thanks for the great work on Ubuntu. I
*love* the way Lucid is turning out.
