Fish shell error: __fish_pwd in command substitution called on standard input

Fish shell error: __fish_pwd in command substitution called on standard input

Since recently I've noticed the following error when starting the fish
shell and on every command execution:

--8<---------------cut here---------------start------------->8---
> fish
fish: 
__fish_pwd
^
in command substitution
	called on standard input

in command substitution
	called on standard input

ambrevar@mimimi > ls
ambrevar@mimimi > ls
booking.html
fish: 
__fish_pwd
^
in command substitution
	called on standard input

in command substitution
	called on standard input
--8<---------------cut here---------------end--------------->8---

Is anyone else seeing this?

not really, but my version could be older. Which version of fish and
which version of guix are you on?

I'm on an older(?) guix version but the same fish version.
Can you describe your problem a bit more?
Are you using fish as a login shell? As a user shell?
Is there anything in $home/.config/fish/ ? Same for $home/.local/share/fish/

I use fish shell as a user shell.
(Actually I only use it for its completion database via emacs-fish-completion -- and the completion does not work beyond file completion).

Neither $HOME/.config/fish/ nor $HOME/.local/share/fish/ exist.

Integration of shells other than Bash are suboptimal in GuixSD at the moment,
you might want to search through the bugtracker and read the tickets I
opened a while back with regards to fish:

https://debbugs.gnu.org/cgi/pkgreport.cgi?include=subject%3Afish;package=guix

Contributions to fix this are welcome.

Thanks for the link to the issues, I'll look into it.
Note that everything was fine by me about a month ago on GuixSD.

After a recent update things are back to normal... Not sure what happened.

OK, found out what's happening thanks to Nils' links.

Running `guix build --check fish` fixes the issue... until next garbage
collection, which explains why I would not always see the issue.

I'll keep discussing this at
https://issues.guix.info/issue/30265.
