Custom keybindings not compiling right with glib-compile-schemas command in Ubuntu 14.04

Hi,

Before I reporting a bug the proper package, I would like ask following question:
I using Ubuntu 14.04 development release, and because more people using my machine, I defined with some settings in a gschema.override file.
Everithing is working right, except custom keybindings related settings applying.
I added following lines my gsettings.override file:
[org.gnome.settings-daemon.plugins.media-keys]
www='<Super><Alt>w'
email='<Super>e'
custom-keybindings = ['/org/gnome/settings-daemon/plugins/media-keys/custom-keybindings/gedit/']

[org.gnome.settings-daemon.plugins.media-keys.custom-keybinding:/org/gnome/settings-daemon/plugins/media-keys/custom-keybindings/gedit/]
name = 'Launch Gedit'
command = 'gedit'
binding = '<Super>g'

My gsettings.override file I putted the /usr/share/glib-2.0/schemas directory. After I added this lines, I ran glib-compile-schemas /usr/share/glib2.0/schemas command, not presented any error messages.
Testing purpose I created a new user, logout, and login the new created username. Optimal case the custom keybinding need applying automaticaly, but this is not happened.
In gnome-control-center keyboard preference pane, keybindings tab the custom shortcuts containing table is empty, containing one row with empty columns.
I doing anything wrong this special key and value pairs definition, or glib-compile-schemas command now have a bug and skyp this type definitions when compiling schemas?

Note: Ubuntu 14.04 use gnome-settings-daemon 3.8.6.1-0ubuntu8 packaged version.

If this problem a bug, what the proper component with need reporting this issue?
