The crash is probably bug 2050865 which is rolling out in automatic updates this week. And since you're using Xorg it's possible that crash is happening even more often than you know, because gnome-shell will just automatically restart on Xorg with apps still running. So if you don't already have the update, please follow: https://bugs.launchpad.net/ubuntu/+source/mutter/+bug/2050865/comments/44
