Comment 8 for bug 223226

I don't see any evidence in the logs to be honest.

Also, I did about 5 upgrade scenarios and in none of them I had to restart KDM (which is indeed not required at all mid-upgrade).
However
  "
  Restarting services possibly affected by the upgrade:
    kdm: stopping...starting...done.
  "
apparently output by libpam0g, is absolutely sensible (KDM uses PAM for authentification, so if PAM gets updated all the services relying on it do as well. But if I recall correctly it only presents a lost if services which _should_ be restarted (editable list actually).

Please confirm that, or clearify what the dialog says _exactly_.
