'dconf' is responsible for handling the program configuration. For
writes, it contacts D-Bus, for read it doesn't need D-Bus.

https://developer.gnome.org/dconf/0.22/dconf-overview.html

If 'dconf' is not available, the program reverts to a 'memory' back-end
and configuration is lost upon exit.

For this reason 'dconf' should be available to all GLib programs
(implicit input to 'glib-or-gtk-build-system'?).
