Runtime crash with Editor example when picking a file

[NOTtheMessiah]

Is your issue REALLY a bug?

• My issue is indeed a bug!
• I am not crazy! I will not fill out this form just to ask a question or request a feature. Pinky promise.

Is there an existing issue for this?

• I have searched the existing issues.

Is this issue related to iced?

• My hardware is compatible and my graphics drivers are up-to-date.

What happened?

I created the following Rustup-based flake.nix for development, and compiled the Editor example, which ran fine until it crashed upon clicking the open file button (which supposedly uses GTK despite being on Plasma).

{
  description = "Iced-rs development environment";

  inputs = {
    nixpkgs.url = "github:NixOS/nixpkgs/nixos-unstable";
    flake-utils.url = "github:numtide/flake-utils";
  };

  outputs = { self, nixpkgs, flake-utils }:
    flake-utils.lib.eachDefaultSystem (system:
      let
        pkgs = nixpkgs.legacyPackages.${system};
        # Read the file relative to the flake's root
        overrides = (builtins.fromTOML (builtins.readFile (self + "/rust-toolchain.toml")));
        libPath = with pkgs; lib.makeLibraryPath [
          # load external libraries that you need in your rust project here
        ];
      in
      {
        devShells.default = pkgs.mkShell rec {
          nativeBuildInputs = [ pkgs.pkg-config ];
          buildInputs = with pkgs; [
            clang
            llvmPackages.bintools
            rustup
            expat
            fontconfig
            freetype
            freetype.dev
            libGL
            pkg-config
            xorg.libX11
            xorg.libXcursor
            xorg.libXi
            xorg.libXrandr
            wayland
            libxkbcommon
            glib
            gtk3
          ];

          RUSTC_VERSION = overrides.toolchain.channel;
          
          # https://github.com/rust-lang/rust-bindgen#environment-variables
          LIBCLANG_PATH = pkgs.lib.makeLibraryPath [ pkgs.llvmPackages_latest.libclang.lib ];
          
          shellHook = ''
            export PATH=$PATH:''${CARGO_HOME:-~/.cargo}/bin
            export PATH=$PATH:''${RUSTUP_HOME:-~/.rustup}/toolchains/$RUSTC_VERSION-x86_64-unknown-linux-gnu/bin/
          '';

          # Add precompiled library to rustc search path
          RUSTFLAGS = (builtins.map (a: ''-L ${a}/lib'') [
            # add libraries here (e.g. pkgs.libvmi)
          ]);
          
          LD_LIBRARY_PATH = pkgs.lib.makeLibraryPath (buildInputs ++ nativeBuildInputs);

          
          # Add glibc, clang, glib, and other headers to bindgen search path
          BINDGEN_EXTRA_CLANG_ARGS =
          # Includes normal include path
          (builtins.map (a: ''-I"${a}/include"'') [
            # add dev libraries here (e.g. pkgs.libvmi.dev)
            pkgs.glibc.dev
          ])
          # Includes with special directory paths
          ++ [
            ''-I"${pkgs.llvmPackages_latest.libclang.lib}/lib/clang/${pkgs.llvmPackages_latest.libclang.version}/include"''
            ''-I"${pkgs.glib.dev}/include/glib-2.0"''
            ''-I${pkgs.glib.out}/lib/glib-2.0/include/''
          ];
        };
      }
    );
}

What is the expected behavior?

Seeing a file dialogue show up

Do you have any log output?

(editor:2816975): GLib-GIO-ERROR **: 16:09:26.783: Settings schema 'org.gtk.Settings.FileChooser' is not installed
Trace/breakpoint trap (core dumped)

The Editor example uses rfd for opening the file picker. Does it still crash if you update the version of rfd used by the example? rfd uses the XDG Desktop Portal by default, instead of GTK directly, since version 0.14, which could fix your issue.
