I have now tried again with `guix environment` instead of using profiles. I 
faced the same issue as with the profile. As soon as emacs-magit is installed 
via guix, I get the error in the `*Messages*` buffer. Then I read about `guix 
shell` and learned, that it is to replace `guix environment`. Didn't know that. 
Guess I should change my usage. So that is what I did next. Changed the `guix 
environment` command in my script to `guix shell`.

It should be reproducible using the following steps, unless guix itself has an 
issue and creates non-reproducible environments:

`channels.scm` file at `~/.guix-extra-profiles/emacs-env/channels.scm`:

         (name 'guix)
         (url"https://git.savannah.gnu.org/git/guix.git")
         (branch "master")
         (commit
           "b731d34ed796ad3ca1cfba6e08369ffd6dcb57bf")
         (introduction

             "9edb3f66fd807b096b48283debdcddccfea34bad"
             (openpgp-fingerprint
               "BBB0 2DDF 2CEA F6A8 0D1D  E643 A2A0 6DF2 A33A 54FA")))))

`env.sh` script to run Emacs at `~/.guix-extra-profiles/emacs-env/env.sh`:

~~~~
#!/usr/bin/env bash

set -Eeuxo pipefail

DIR="~/.guix-extra-profiles/emacs-env/"

guix time-machine \
      --channels="${DIR}/channels.scm" -- \
      shell \
      --cores=4 \
      --manifest="${DIR}/manifest.scm" -- \
      emacs
~~~~

With those in place run:

~~~~
bash ~/.guix-extra-profiles/emacs-env/env.sh
~~~~

However, I have now found out, that the `-C` flag is `--container`, which I am 
not using! So I tried to use `--container` with the `guix shell` command and, 
what a surprise, the error in Emacs disappeared!

Now of course the question is, how does `--container` affect the `emacs-magit` 
package? What is Emacs reading, that affects Magit and even prevents it from 
loading the dependency `git-commit`?

If I find out more, I'll let you know.

Best regards and thanks for the patience,
Zelphir
