Most likely fixed by https://bugzilla.gnome.org/show_bug.cgi?id=755096 .
Thanks Jonas - that does seem like the same bug. The fix landed after 3.18.0, so will be in 3.18.1 or if we make a patched Fedora mutter package.
Another user experienced a similar problem: Fedora 23, Gnome-shell on wayland (started via gdm on wayland). Pressed Fn+F7 on my Thinkpad, attempting to switch to external-only display mode. Caused immediate crash back to gdm. reporter: libreport-2.6.3 backtrace_rating: 4 cmdline: /usr/bin/gnome-shell --wayland --display-server crash_function: g_hash_table_lookup_node executable: /usr/bin/gnome-shell global_pid: 2192 kernel: 4.2.3-200.fc22.x86_64 package: gnome-shell-3.18.1-1.fc23 reason: gnome-shell killed by SIGABRT runlevel: N 5 type: CCpp uid: 1026
Since this seems to reproduce with the above linked fix in place, I suspect it instead is this one: https://bugzilla.gnome.org/show_bug.cgi?id=756548
mutter-3.18.1-3.fc23 has been submitted as an update to Fedora 23. https://bodhi.fedoraproject.org/updates/FEDORA-2015-bebede9f5b
Nominating as a final FE; Wayland stuff can't block release as it's not default, but FE to fix crashers sure seems reasonable. It's definitely possible people (inc. reviewers) might install the live and immediately test Wayland without updating, and if it crashes, that looks bad.
+1 FE
+1 FE with the reasoning from c#21
