And do you actually use OpenCL

I was advised to ask here instead of https://matrix.to/#/#users:nixos.org.

I installed home-manager flake on Pop!_OS 22.04 a few weeks ago and since then I got a few programs crashed when opening a home dir. I finally got to the bottom of this and renaming ~/.local/state/nix/profiles/profile to anything else fixes it. Or removing ~/.nix-profile/share from XDG_DATA_DIRS. Can someone explain why that happens and how can I fix this without launching all the problematic apps with env?

Theme files not being found still should not cause GLib to crash. Could you try getting more lines of backtrace in gdb? Ideally, with debug symbols but it does not look like they are easy to come by in Pop!_OS https://github.com/pop-os/pop/issues/2797

I "fixed" it with

fx = ''env XDG_DATA_DIRS=$(echo $XDG_DATA_DIRS | sd "$HOME/.nix-profile/share:" "") $SHELL'';
