Describe the bug

when building libsForQt5.kcmutils from nixpkgs, during postPatchMkspecs, Lix errors out with

error: error reading daemon response: error: stream ended unexpectedly

Steps To Reproduce

nix-build -I nixpkgs=https://github.com/nixos/nixpkgs/archive/2fc6539b481e1d2569f25f8799236694180c0993.tar.gz '<nixpkgs>' -A libsForQt5.kcmutils

Expected behavior

the build should succeed.
fwiw, kdePackages.kcmutils builds just fine with the --check flag.

nix --version output

## Describe the bug when building `libsForQt5.kcmutils` from `nixpkgs`, during `postPatchMkspecs`, Lix errors out with ``` error: error reading daemon response: error: stream ended unexpectedly ``` ## Steps To Reproduce ``` nix-build -I nixpkgs=https://github.com/nixos/nixpkgs/archive/2fc6539b481e1d2569f25f8799236694180c0993.tar.gz '<nixpkgs>' -A libsForQt5.kcmutils ``` ## Expected behavior the build should succeed. fwiw, `kdePackages.kcmutils` builds just fine with the `--check` flag. ## `nix --version` output ``` nix (Lix, like Nix) 2.94.0 System type: x86_64-linux Additional system types: i686-linux, x86_64-v1-linux, x86_64-v2-linux, x86_64-v3-linux, x86_64-v4-linux Features: gc, signed-caches System configuration file: /etc/nix/nix.conf User configuration files: /home/flippette/.config/nix/nix.conf:/etc/xdg/nix/nix.conf Store directory: /nix/store State directory: /nix/var/nix Data directory: /nix/store/vr4a39d4bw01793jl4qap839rlvmc143-lix-2.94.0/share ``` ## Additional context <details> <summary>this log appears in `journalctl` when Lix crashes</summary> ``` Feb 26 17:26:26 okaeri systemd-coredump[47963]: Process 42577 (nix) of user 0 dumped core.

this is fixed in lix main, where it produces the following error:

2.95 should be release soonish and make that fix available, but we may also backport the fix the 2.94. @ma27?
