Sorry the above message is misleading: I did not realize that I already
had a "Guix REPL" already open, I killed the REPL and this is the error
message I get when I start "M-x guix" and then try to gel my profiles
list:

--8<---------------cut here---------------start------------->8---

Starting Guix REPL ... [3 times]
guix-geiser-eval: Error in evaluating guile expression: ice-9/boot-9.scm:1685:16: In procedure raise-exception:
Unbound variable: %max-returned-list-size

Entering a new prompt.  Type `,bt' for a backtrace or `,q' to continue.
scheme@(guile-user) [1]> 

--8<---------------cut here---------------end--------------->8---

(That's the same I get when I start emacs-guix in a guix shell)

This is the error I get in the "Guix REPL" buffer:

--8<---------------cut here---------------start------------->8---

scheme@(guile-user)> ,m (emacs-guix)
While executing meta-command:
no code for module (guix ui)
scheme@(guile-user)> 

--8<---------------cut here---------------end--------------->8---

this is the backtrace

--8<---------------cut here---------------start------------->8---

scheme@(guile-user)> ,bt
           2 (eval (#<procedure 7fae8f34be70 at <unknown port>:8:56 ()>) #<directory (guile-user) 7fae9151fc80>)
In current input:
     8:23  1 (_)
In ice-9/boot-9.scm:
  1685:16  0 (raise-exception _ #:continuable? _)
scheme@(guile-user) [1]> 

--8<---------------cut here---------------end--------------->8---

if I "manually" give the same command in the REPL buffer, I get no
error:

--8<---------------cut here---------------start------------->8---

scheme@(guile-user)> ,m (emacs-guix)
scheme@(emacs-guix) [1]> 

--8<---------------cut here---------------end--------------->8---

then I try again to list all my profiles via "M-x guix" (then select "P"
and "a") but I get the following message:

--8<---------------cut here---------------start------------->8---

guix-geiser-eval: Error in evaluating guile expression: ice-9/boot-9.scm:1685:16: In procedure raise-exception:
Unbound variable: user-profiles

Entering a new prompt.  Type `,bt' for a backtrace or `,q' to continue.
scheme@(emacs-guix) [2]> 

--8<---------------cut here---------------end--------------->8---

But now the "Guix REPL" does not give any error, it's "stopped" at the
same prompt given above ("scheme@(emacs-guix) [1]>")

[...]

Thanks! Gio'
