Noble spice-vdagent crash crashes xorg

[Mike Ferreira]

This is on 'debian release' upgraded from Mantic to Noble, which I keep persistent to test the Noble Upgrades from day-to-day.

Intermittent crashes, which results in the desktops crashing and returning back to the GDM3 graphical login.

I am not sure if, since a VM, and Spice, if it is a KVM host problem, or if a Noble problem. The host is 22.04.3:

Note that KVM machine / OS templates, currently, only go to Ubuntu 23.10, which this one is set to. If I set them to VGA, instead of QXL, it doesn't seem to happen.
