Ah, that assert is in mutter.

FWIW, that code was added in
https://gitlab.gnome.org/GNOME/mutter/commit/9b903e93e3cd0601b436c55b7cea1fbecf29895f
So... uh... maybe some icon on my system is making it unhappy?
I gather gtk-update-icon-cache is involved?
buildbot@rbb-ubu1804-3:~$ ls -l /usr/share/icons/*/*.cache

-rw-r--r-- 1 root root 55040 Apr 24 14:57
/usr/share/icons/ubuntu-mono-light/icon-theme.cache
But now I can't get it to crash anymore.
so maybe I accidentally fixed it by installing some package that updated the
icon caches...?
$ grep hicolor /var/log/dpkg.log
...
2018-04-24 14:42:29 status installed hicolor-icon-theme:all 0.17-2
...
2018-04-24 15:33:00 status installed hicolor-icon-theme:all 0.17-2
...
2018-04-25 09:40:43 status installed hicolor-icon-theme:all 0.17-2
Hrmf. My uneducated theory is that an icon cache was corrupt, but is fine now.
Who knows?

Title:
gnome-shell crashes after a few seconds
Status in gnome-shell package in Ubuntu:
New
Bug description:
I have a fleet of Dell T7500's, a few Dell 3620's, a Skull Canyon, and
a Hades Canyon, and a few other odds and ends, running a mix of ubuntu
16.04 and 17.10.
On one of the T7500 ubuntu 17.10 boxes (nvidia 340 package, Quadro K5000
card),
I did sudo "do-release-upgrade -d". Went fine, but on reboot, the desktop
would
come up for about ten seconds, then the system would shut down.
Did
systemctl set-default multi-user.target
then removed all traces of the proprietary driver with
sudo apt remove --purge nvidia-340 nvidia-opencl-icd-340 nvidia-settings
nvidia-384 nvidia-opencl-icd-384 nvidia-prime libcuda1-340
and rebooted. Logging in to the console and running 'startx' reproduces the
problem reliably, and does not shut down the system.
Installing lwm, and a .xinitrc that started an xterm, let startx succeed, and
the system was stable running firefox, so it's not an obvious graphics
problem.
