bug#54867: "You found a bug" during guix pull on freshly executed qemu image

[Carlos Fernández Llamas]

Hi there!,

Just encountered an error while giving Guix a try.

My steps:
- Downloaded the Guix 1.3.0 qcow2 image: 
https://ftp.gnu.org/gnu/guix/guix-system-vm-image-1.3.0.x86_64-linux.qcow2
- Executed it on Debian bullseye using qemu-system, as explained here: 
https://guix.gnu.org/manual/en/html_node/Running-Guix-in-a-VM.html (side note: 
running `xz -d` with the downloaded image didn't work, complaining about it not 
being the correct format. Used it directly without decompressing and guix 
started properly anyway, so ¯\_(ツ)_/¯)
- Configured keyboard to the Spanish layout using the GUI.
- Opened a terminal and executed `guix pull`

As a result, got the following output ending with "You found a bug" and a 
suggestion to report it here, so, here we are :)
