Ludo rebuilt the affected file on berlin.guixsd.org, so you garbage
collect 'njdhsdv216hyk23nfrc7wh9hbq17ymxk-compute-guix-derivation' and
then try again.

If that doesn't work yet, rebuild one of the derivers locally with
--no-substitutes.

It’s possible that you had a cached narinfo with zero references in
/var/guix/substitute/cache.

Right now I get:

$ --8<---------------cut here---------------start------------->8---
$ wget -q -O - https://berlin.guixsd.org/njdhsdv216hyk23nfrc7wh9hbq17ymxk.narinfo |grep ^Ref
References: 466iifqhyq99qy41km5h6vy6nn6a5m0b-module-import-compiled 6mfd4f8gy11rgn2xk00cnslmrslg9w7h-guile-2.2.3 ak8kcfpyz76vhn9g2giygrxpx9zfi9zw-module-import qbzw2ygy1nq2h0nq6sl9cgg1c5mq5g8z-guile-gcrypt-0.1.0
--8<---------------cut here---------------end--------------->8---

This kind of problem can propagate to every user who trusts the build
farm, so it’s obviously a serious issue.

I’d like to understand how this happened in the first place but all I
can think of is some database corruption or hardware failure.  The
reference scanner in libstore/references.cc cannot be blamed AFAICS.
