Steps To Reproduce
absolutely no idea, except maybe checkout https://github.com/zseri/nixos-configs/commit/897aa9e081db3e82d962158960104a0f6c70e4f4, and try the command given above to build my main system. might take a few days, tho...
Expected behavior
nix client shouldn't segfault ;-)
nix-env --version output
