If I had to guess, the first stack trace seem to blame:

The other are just waiting on stuff. I tried to get debug symbols using the instructions in https://discourse.nixos.org/t/how-to-investigate-gnome-crashing/19726/2, but it does not seem to work.

By the way, same thing on unstable.

Do you mean you tried adding the following to your configuration, tried logging into a Flashback session and then looked at the appropriate coredumpctl trace by coredumctl gdb <pid> and then entered bt?

  environment.systemPackages = with pkgs; [
    gdb
    # To link debug symbols to path where gdb can see them.
    glib
    gnome.gnome-flashback
  ];

  environment.enableDebugInfo = true;

  nixpkgs.overlays = [
    (final: prev: {
      # These three packages contain debug symbols since NixOS 22.11.
      # You do not need this overlay on that or later versions.
      gnome = prev.gnome.overrideScope' (gfinal: gprev: {
        gnome-flashback = gprev.gnome-flashback.overrideAttrs (attrs: {
          separateDebugInfo = true;
        });
      });
    })
  ];
}

What specificity does not work?
