Nixpkgs: rhythmbox should get dconf as dependency

[castilma]

EDIT: the original problem got fixed by installing dconf. it should be added as dependency to rhythmbox.

Issue description

rhythmbox spits out a lot of warnings and then segfaults after a few seconds.

Steps to reproduce

• nix-env -iA nixos.rhythmbox
• enable 'start gnome runtime environment' in xfce sessionsettings>advanced
• nix-env -iA nixos.gnome3.gnome_settings_daemon
  because i thought it would remove most warnings and think that this belongs to the runtime environment of gnome, what the xfce setting would require. i have no idea if xfce found it, though. (where can i find xfce errors and warnings?)
• start rhythmbox
  it spits out:

$ rhythmbox

Side questions

if this problem stems from missing packages, shouldn't the rhythmbox nix expression contain the dependency?

amarok seems to have a similar problem: #16588. -> Am I (and others) experiencing edge cases or is nixos not that stable yet?

since we have a declarative system, is it preferred to include the system and user manifest in a bug report?

Technical details

• System: NixOS: `17.03.1931.8b8977f9ff (Gorilla)
• Nix version: nix-env (Nix) 1.11.14
• Nixpkgs version: "17.03.1931.8b8977f9ff"
• Sandboxing enabled: build-use-sandbox = false

try install nix-env -i dconf

[castilma]

this solved it. dconf should be added as dependency!

Same happens with plank, it doesn't crash, but I can't change any settings:

Installing gnome3.dconf fixed it for me!

[jtojnar]

gnome3.dconf is a system service that needs to be added to services.dbus.packages by your desktop environment. If you create your own environment, you will need to add it yourself (adding programs.dconf.enable = true; to configuration.nix should work). Nix does not contain a mechanism for representing a dependency on a service.
