Comment 2 for bug 1122028

This bug was also reported in GNOME's bugzilla:
https://bugzilla.gnome.org/show_bug.cgi?id=693149

Let me add that if the locks are removed from the /etc/dconf files, and then the user changes the value manually, for example to 3 minutes, then this is the result:

$ dconf read /org/gnome/desktop/session/idle-delay
uint32 180
$ gsettings get org.gnome.desktop.session idle-delay
uint32 180

But if the locks are then restored (by editing the files and then running dconf update):

$ dconf read /org/gnome/desktop/session/idle-delay
10
$ gsettings get org.gnome.desktop.session idle-delay
uint32 600
