With this commit, I still get the backtrace in the original report of
this bug.

I ran `guix pull` and confirmed the changes were in ~/.config/guix/latest.

I cleared the cache at /vat/guix/substitute/cache.

Then, I updated --substitute-urls in the daemon invocation and reloaded the
daemon, and then did `guix build hello`.

Did I miss a step?
