Hello,

I get the following error when running ``guix --version | head -n 1''. I
can get similar after replacing ``--version'' with ``--help''. Also, the
error is nondeterministic. Any idea?


$ LC_ALL=C guix --version | head -n 1

Now it’s fixed.

--8<---------------cut here---------------start------------->8---
$ guix --version | awk '{print $4; exit}'

--8<---------------cut here---------------end--------------->8---

Therefore, closing this old bug:

Feel free to reopen if I’m missing something.
