Gnome-shell crashing when the dash-to-dock is set to autohide

[petr-hybler-ofti]

When I set the dash-to-dock to autohide and I suspend the laptop, upon awaking it, the gnome shell crashing .. in the gnome-shell journalctl I can see this:

Steps to repeat:

• enable Intelligent autohide
• suspend the laptop
• awake the laptop

• CTRL ALT F3 -> login as the same user ... run sudo killall -1 gnome-shell
• CTRL ALT F2 -> when the gnomeshell restarts, it's all back to normal

$ gnome-shell --version GNOME Shell 42.9
System: ubuntu 22.04.4 LTS
Windowing system: X11

PS: Wayland seems to be working fine tho

This looks like a duplicate of #1992

According to the Ubuntu bug, it might be fixed in Ubuntu 24.04 and later. Or you can just be sure to disable all unused dock extensions.
