Bug#1056167: /usr/libexec/gnome-initial-setup: Fails to boot into desktop environment due to SIGSEGV around cc-input-chooser.c

Sat Nov 18 04:19:04 GMT 2023

Package: gnome-initial-setup
Version: 43.2-6
Severity: important

Dear Maintainer,

   * What led up to the situation?

I had a fully working & configured system with gnome.

I performed automatic updates through the software center and did the
suggested restart. These updates do not seem to be related to the crash
though:

    Start-Date: 2023-11-17  22:24:40
    Commandline: packagekit role='update-packages'
    Upgrade: libjavascriptcoregtk-4.1-0:amd64 (2.42.1-1~deb12u1, 2.42.2-1~deb12u1), gir1.2-javascriptcoregtk-4.0:amd64 (2.42.1-1~deb12u1, 2.42.2-1~deb12u1), gir1.2-javascriptcoregtk-4.1:amd64 (2.42.1-1~deb12u1, 2.42.2-1~deb12u1), gir1.2-webkit2-4.0:amd64 (2.42.1-1~deb12u1, 2.42.2-1~deb12u1), gir1.2-webkit2-4.1:amd64 (2.42.1-1~deb12u1, 2.42.2-1~deb12u1), libjavascriptcoregtk-6.0-1:amd64 (2.42.1-1~deb12u1, 2.42.2-1~deb12u1), libjavascriptcoregtk-4.0-18:amd64 (2.42.1-1~deb12u1, 2.42.2-1~deb12u1), libwebkit2gtk-4.1-0:amd64 (2.42.1-1~deb12u1, 2.42.2-1~deb12u1), libwebkit2gtk-4.0-37:amd64 (2.42.1-1~deb12u1, 2.42.2-1~deb12u1), libwebkitgtk-6.0-4:amd64 (2.42.1-1~deb12u1, 2.42.2-1~deb12u1)
    End-Date: 2023-11-17  22:24:46

When the automatic login kicked in after this reboot, I got a segfault
in gnome-initial-setup. Full stack trace:

   * What exactly did you do (or not do) that was effective (or
     ineffective)?

1. I've uplugged all USB devices, turned off all paired bluetooth
devices, and rebooted. This was ineffective

2. I've uncommented `en_US.UTF-8 UTF-8` from `/etc/locale.gen` and run
`sudo locale-gen`, then rebooted. This was ineffective, although it did
update the results of `locale -a`

   * What was the outcome of this action?

No improvement.

   * What outcome did you expect instead?

SIGSEGV to be resolved, so that I don't recieve a SIGSEGV on the
gnome-initial-setup process, and so that I don't see a sad computer
screen stating "Oh no! Something has gone Wrong. A problem has occured
and the system can't recover. Please log out and try again."
