Title:
  gnome-shell (login screen) crashes with SIGSEGV in
  __GI_getenv("EXPAT_ACCOUNTING_DEBUG")

Status in gnome-shell package in Ubuntu:
  Incomplete

Bug description:
  Last time I hacked around a bug like this, it had portions in PAM,
  apparmor, Seahorse, and Gnome so this time I'd like someone more
  focused on broad stability to look at things.

  The problem is simple.  Before the upgrade to 23.10, I could log in
  using the "Ubuntu", "Ubuntu on X.org". "Gnome", and "Gnome on X.org"
  WMs.  Now I can't.  I can still login using XFCE and TTY.
