Bug 1209203

Approximately since an update past Thu 2023-03-09 I can't log into GNOME session, gnome shell/gdm crashes.

I could extract the following stacktrace with debuginfo:

I'm not sure if related or just red herring (those messages were present even _before_ gnome-shell started to crash) but there were also some X/Mesa errors:
