I have the same crash as Rachel whenever I unplug the DVI from my NVidia graphics card or switch the KVM to another monitor. I use Ubuntu 17.10 latest, with mutter 3.26.2-0ubuntu0.1 installed. This does not fix the crash.
I also get the assertion: meta_monitor_manager_get_logical_monitor_from_number: assertion '(unsigned int) number < g_list_length (manager->logical_monitors)' failed I could fix the issue by building my own mutter based on 3.26.2-0ubuntu0.1 but with the patch 3572502 from https://git.gnome.org/browse/mutter/commit/?id=3572502 applied. The patch applies cleanly and the crash is gone.
