The crash occurs (during the software updates) regardless of whether I run the "gnome-shell --replace" command. I was only running the command before installing the software updates (and therefore, before the crash happened) in one specific session per Ubuntu release in order to get debug information when the crash happens (above). I would never run it in a normal scenario.
I crashed gnome-shell on Ubuntu 16.04 again (without running the "gnome- shell --replace" command) and added a symbolic stacktrace, which I managed to upload to Launchpad using the ubuntu-bug command (I needed to enable Apport in 16.04 LTS by commenting-out a line in /etc/apport/crashdb.conf).
