Package: gnome-shell
Version: 3.34.4-1
Severity: critical
Justification: breaks the whole system

Dear Maintainer,

After today's upgrade the system hangs with

GnomeDesktop:ERROR:../libgnome-desktop/gnome-bg-slide-show.c:86:gnome_bg_slide_show_set_property: 
assertion failed: (GNOME_BG_IS_SLIDE_SHOW (object)).

This happens with and without wayland.

The gnome-shell errors about OpenGL and glamor and keymap are normal.
