22.04: Opening USB drives in Nautilus crashes Gnome Shell

[leviport]

Steps to reproduce:

1. During a user session, plug in a USB drive
2. Open Nautilus
3. Click on the USB drive in the sidebar on the left
4. Gnome Shell will crash and end up at the "Oh no! Something has gone wrong." screen with a "Log out" screen.

cding into the drive and running nautilus . also crashes Gnome Shell.

Can confirm this happens under a virt-manager VM with an attached ISO image as well. The same thing occurs when clicking on the drive in the dock, too (as it launches Nautilus).

dmesg shows a segfault by GNOME shell in libglib:

These seems to happen if the cosmic-dock extension is enabled and not otherwise, so something there must be causing it.

These seems to happen if the cosmic-dock extension is enabled and not otherwise, so something there must be causing it.

I also get logged out if I click on the drive's icon in the dock. Disabling "show mounted drives" in Cosmic dock's settings stops this from occurring and also stops the problem in Nautilus.

[ids1024]

This is probably fixed upstream in https://github.com/micheleg/dash-to-dock/tree/ubuntu-dock, but rebasing the cosmic-dock changes on that is non-trivial.

[ids1024]

This should be addressed once the work in https://github.com/pop-os/cosmic-dock/pull/124 is done.
