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).

I've found that I was able to replicate the error by following these steps: Download and install a copy of Ubuntu Gnome 16.04.2 in VirtualBox. Open a screen displaying App icons in a menu, such as the app grid in the Gnome Shell overlay or the Arc Menu Gnome Shell extension (https://extensions.gnome.org/extension/1228/arc-menu/). Install all the latest software updates from the Software Updater or Synaptic. Upgrading all the packages between 16.04.2 to 16.04.3 seems to over-load Gnome Shell and cause the crash in the middle of the installation process. This crash always seems to occur after opening a screen with app icons and I'm not sure why. I've attached my .crash file updated with a symbolic stack trace.I hope this info and my attachment proves helpful in fixing the issue.
