Applications fails to start because dconf/gconf is missing

If you are getting an error like:

GLib.GException: Failed to contact configuration server; the most common cause is a missing or misconfigured D-Bus session bus daemon. See http://projects.gnome.org/gconf/ for information

when running Gtk applications you need to add gconf to the list of dbus packages in your configuration.nix. In Gnome3 gconf was replaced by dconf. For simplicity you can just add both:

services.dbus.packages = with pkgs; [ gnome3.dconf gnome2.GConf ];
