You can try with one of the examples of guix, if you don't want to risk
anything with your config! Here is lightweight-desktop.tmpl, and the
edited lightweight-desktop-with-guile.tmpl. 

If you run 

    guix system docker-image lightweight-desktop-with-guile.tmpl

you get the error.

If you run

    guix system docker-image lightweight-desktop.tmpl

it works.

Also, I must say that the problem also happens with any package that
has guile has a propagated input, but the root of the problem seems to
be guile.
