Not succeeded in reproducing this again after rebuilding GNOME Shell with ASAN_OPTIONS=detect_leaks=0 CFLAGS="-fsanitize=address -fsanitize=return -fsanitize=bounds -fsanitize=object-size". I do now manage to trigger debian bug 823216 quite reliably now, with the difference that I can log on again immediately. It is usually the user GNOME Shell and XWayland which crash, but at least once the gdm ones crashed.

I trigger this by opening a few applications (Firefox with a few windows seems to make it easier to reproduce) and repeatedly opening and closing the laptop lid. It seems that, as per systemd logind settings this should not trigger a suspend when docked, but occasionally it does. The xwayland termination happens just before this (as observed from an ssh session on my other laptop: I can see the results just before the session stops responding due to the suspension).
