Bug Description

# lsb_release -rd
Description: Ubuntu 17.10
Release: 17.10

# apt-cache policy gnome-shell
gnome-shell:
  Installed: 3.26.1-0ubuntu4
  Candidate: 3.26.1-0ubuntu4
  Version table:
 *** 3.26.1-0ubuntu4 500
        500 http://dk.archive.ubuntu.com/ubuntu artful/main amd64 Packages
        100 /var/lib/dpkg/status

This happens 2-3 times per day it seems. Sometimes when working the whole systems seems to become unresponsive. My cursor can still be moved. But everything else is frozen (unresponsive). After 30 secs the problems seems to be resolved. And maybe a minute after that i get the prompt to report this problem.

Let me know if you need more info
