pixel saver crashing on gnome-shell 3.14

[deadal nix <deadalnix gmail com>]

Hi all,

I'm the main dev of pixel saver, a gnome shell extension. It is crashing gnome-shell 3.14 .

The crux of the problem seems to be fetching infos from gio:

const DCONF_META_PATH = 'org.gnome.shell.overrides';
let order = new Gio.Settings({schema_id: DCONF_META_PATH}).get_string('button-layout');

This is generating the following error:
GLib-GIO-ERROR **: Settings schema 'org.gnome.shell.overrides' does not contain a key named 'button-layout'

And soon after this, gnome-shell hard crashes.

$ gsettings get org.gnome.shell.overrides button-layout

tells me the key do not exists. However, I can go look for it in dconf-editor and windows seems to react to it (BTW, it is now taken into account in the title bar, thank you guys !)

The problem is not specific to my installation, as various users report the same thing.

Any idea what might be going on ? This extension is fairly popular and is affecting gnome users.
