Bug Description

In Quantal in Raring, gnome-screensaver no longer auto starts in the Unity session because the .desktop file contains the following line:

AutostartCondition=GNOME3 if-session gnome-fallback

This results in screen locking being broken.

Steps to reproduce:

1- Reboot
2- Login to session
3- Wait 10 minutes

Expected results:
- gnome-screensaver process autostarted in session
- screen locks after 10 minutes

Actual results:
- gnome-screensaver process doesn't get autostarted
- screen only blanks after 10 minutes, and doesn't lock.

Manually locking the screen results in the gnome-screensaver process being spawned, which fixed screen locking for the remainder of the session.
