Subject: bug#59579: installing zbar prevents gdm to start on Ubuntu 22.04 foreign distro

From: Clément Lassieur <[email-masked]>

Severity: serious

Steps to reproduce:

> - install Ubuntu 22.04
> - install Guix package manager
> - guix package -i zbar
> - reboot

Expected result

> boot

result

> login loop

It's very difficult to pin the issue down to a guix package being installed.

I imagine the bug would not happen if ~/.guix-profile/share was not in XDG_DATA_DIRS.
