Thanks. I have found automated reports of this crash are being collected in: https://errors.ubuntu.com/problem/08889c1b3f4726cedeae593a806928a689c70aaa
The good news is that it seems to have been fixed around Ubuntu 17.10, with zero reports in 18.04 onward. The bad news is that without knowing what fixed it we cannot backport a fix to 16.04. So I can only recommend using Ubuntu 18.04 where this crash does not happen. ** Description changed: + https://errors.ubuntu.com/problem/08889c1b3f4726cedeae593a806928a689c70aaa + lsb_release -rd Description: Ubuntu 16.04.4 LTS Release: 16.04 apt-cache policy gnome-shell gnome-shell: - Installed: 3.18.5-0ubuntu0.3 - Candidate: 3.18.5-0ubuntu0.3 - Version table: - *** 3.18.5-0ubuntu0.3 500 - 500 http://us.archive.ubuntu.com/ubuntu xenial-updates/universe amd64 Packages - 100 /var/lib/dpkg/status - 3.18.4-0ubuntu3 500 - 500 http://us.archive.ubuntu.com/ubuntu xenial/universe amd64 Packages + Installed: 3.18.5-0ubuntu0.3 + Candidate: 3.18.5-0ubuntu0.3 + Version table: + *** 3.18.5-0ubuntu0.3 500 + 500 http://us.archive.ubuntu.com/ubuntu xenial-updates/universe amd64 Packages + 100 /var/lib/dpkg/status + 3.18.4-0ubuntu3 500 + 500 http://us.archive.ubuntu.com/ubuntu xenial/universe amd64 Packages Happened for no reason that I can see.
