"I upgraded from Leopard to Snow Leopard last week. By accident I clicked on the 'guest log-in' icon on my MBP 30 minutes ago. After about 1 minute it automatically returned to the log-in screen, without showing up the guest desktop, so I decided to click on the 'guest log-in' again. This went pretty smooth and when I logged out the message appeared that all the 'guest log-in data' wouldn't be saved, but returned to normal. When logging in to my regular account, everything was gone. I don't use filevault. Nothing has been renamed to something else. My home-directory still exists under /Users/username but it is just empty."
