I see the similar D-Bus error for another package. I'm able to workaround it by installing gconf with nix-env along with instructions from https://nixos.org/wiki/Solve_GConf_errors_when_running_GNOME_applications.

Could you please test if that works for you?

[rasendubi]

Update: installing gnome.GConf or gnome3.gconf either globally or locally through nix-env is the only thing that was required for me. I've fixed the issue for my package by adding gconf to propagatedUserEnvPkgs. I've tested and this works for guake, too.

I've provided a patch https://github.com/NixOS/nixpkgs/pull/16670.
