GTK file dialog not working in bitwig studio 4.0.1

landorg · August 20, 2021, 4:08pm

Hello fellow nixOS users

Since the new version of bitwig-studio from nixos unstable the gtk file dialog isn’t working anymore.

NixOS/nixpkgs/blob/be388e6435e389ef5f9f5f5f394d28c9d6d3801f/pkgs/applications/audio/bitwig-studio/bitwig-studio4.nix

{ stdenv, fetchurl, alsa-lib, cairo, dpkg, freetype
, gdk-pixbuf, glib, gtk3, lib, xorg
, libglvnd, libjack2, ffmpeg
, libxkbcommon, xdg-utils, zlib, pulseaudio
, wrapGAppsHook, makeWrapper }:

stdenv.mkDerivation rec {
  pname = "bitwig-studio";
  version = "4.0.1";

  src = fetchurl {
    url = "https://downloads.bitwig.com/stable/${version}/${pname}-${version}.deb";
    sha256 = "sha256-yhCAKlbLjyBywkSYY1aqbUGFlAHBLR8g8xPDIqoUIZk=";
  };

  nativeBuildInputs = [ dpkg makeWrapper wrapGAppsHook ];

  unpackCmd = ''
    mkdir -p root
    dpkg-deb -x $curSrc root

While I can manually run it from the command line like that:

[I] ➜ /nix/store/vwhrcd9jiy0gc3jb2b60v4p02qibikdy-bitwig-studio-4.0.1/libexec/bin/show-file-dialog-gtk3

When I try to open it from the app I am getting that error:

All the resources I have found with similar problems recommend adding something like that to the package but the bitwig-studio package already has these

nativeBuildInputs = [
    wrapGAppsHook
  ];

  buildInputs = [
    gtk3
  ];

not sure what this does:

  dontWrapGApps = true; # we only want $gappsWrapperArgs here

but it’s not working without.

Woud be great if someone could give me a pointer.
Thanks
