three guest accounts on lightdm login screen after "sign out"

[Pascal Rosin]

Using Kubuntu 12.10 Beta 1.

After "sign out" from guest account, there are three guest account buttons on the login screen. After a reboot everything is normal (only one guest account button).

Steps to reproduce:
1. Start computer
2. On the login screen ḱlick on "Guest", then on "login"
3. Open "K" menu, then "Exit" then "sign out" (menu point names can be different, I am on a german installation and translating back to english).
4. You are on the login screen again and there are tree "Guest" user buttons not one as normal.

EcryptfsInUse is true for the other (my normal) user's account but not for the guest account

Ehm. Are you sure you were using KDM? Because that report of yours says:
Package: kdm (not installed)
and 12.10 by default uses lightdm rather than KDM.

yes you are right it is lightdm. I did not notice, that lightdm is the standard loginmanager now.
