Comment 13 for bug 435930

This needs, at least, a warning at log-out time as well.

The new warning at log-in time is better than no warning at all but is still TOTALLY INSUFFICIENT. Ubuntu deletes the user's data at log-out time. The user that saved work and logged out may not be the user that launched the guest session: "here, use this computer, I've launched a guest session for you". Or the user that saves work may leave the computer logged in, intending to come back to it, maybe knowing that their work will be lost if they log out or maybe not knowing; and then their friend comes along and logs out the session, and gets not even a warning that their friend's data is now being deleted.
