Status changed to 'Confirmed' because the bug affects multiple users.

I have something to add:
- It happens only if the Ubuntu Dock is active
- It can happen by just opening and closing the folder
- By analyzing htop you can see gnome-shell is using 100% CPU after it has crashed
- It seems to be related to the scaling bug that happens when you open and close folders

[Daniel van Vugt (vanvugt)]

If the problem is gnome-shell using 100% CPU and not responding then please kill it in a way that will create a crash file like:

  killall -USR2 gnome-shell

and then follow these instructions:
