Bug Description

With zesty's current mutter 3.23.91-0ubuntu1, Budgie crashes after trying to launch some apps.

Downgrading mutter to 3.23.90-0ubuntu2 fixes this.

After a cold reboot + restart, I got this crash, and had to re-login, and then the same happened.

I then logged in on my plain Ubuntu desktop.

Ran a git bisect on mutter:

https://github.com/GNOME/mutter/commit/383ba566bd7c2a76d0856015a66e47caedef06b6

confirmed - final git bisect bad displays the above commit

I built a local mutter v2.23.91 package with a reverse patch of that commit. All is well. I really don't understand though the code behind that commit nor the logic in the linked bugzilla report though :(
