Comment 3 for bug 1270788

Well, users who don't pay attention will always run into trouble irrespective of the desktop design.

lightdm, and with that the guest session feature, is included in several distributions, for example Ubuntu with Unity, Xubuntu, Lubuntu and Kubuntu, and I think they may use different software for logging out from a session. Consequently, fixing this bug will probably require changes in several packages, and I don't think lightdm is one of them. (Still keeping lightdm as affected package for now.)

Julian, considering that you seem to find the issue important, would you like to work with it?
