GNOME/Wayland from Fedora 27. When the crash happened, no specific application was opened, I was simply testing a Wacom tablet buttons (I just mapped some letters to a button and was clicking them in a terminal to see if they appeared). Then it crashed after a few minutes. > $ coredumpctl list > [...] > Fri 2017-12-01 23:09:10 CET 14052 1000 1000 6 present /usr/bin/Xwayland > Fri 2017-12-01 23:09:13 CET 14002 1000 1000 5 present /usr/bin/gnome-shell $ coredumpctl gdb /usr/bin/Xwayland PID: 14052 (Xwayland) UID: 1000 (jehan) GID: 1000 (jehan) Signal: 6 (ABRT) Timestamp: Fri 2017-12-01 23:09:10 CET (1h 49min ago) Command Line: /usr/bin/Xwayland :0 -rootless -terminate -core -listen 4 -listen 5 -displayfd 6 Executable: /usr/bin/Xwayland Control Group: /user.slice/user-1000.slice/session-5.scope Unit: session-5.scope Slice: user-1000.slice Session: 5 Owner UID: 1000 (jehan) Boot ID: 527685df08a54928b34265eb31732096 Machine ID: 91a227afc4144f14aff99675126a3873 Hostname: DarkMarmot Storage: /var/lib/systemd/coredump/core.Xwayland.1000.527685df08a54928b34265eb31732096.14052.1512166150000000.lz4 Message: Process 14052 (Xwayland) of user 1000 dumped core.

Changing component to Xwayland since the original crash seems to have happened there. Also setting to critical since it crashes GNOME and everything in it. Moreover I am not sure at all there is any relation with Wacom. That's just what I was doing at the time (testing Wacom buttons) but there don't look to be anything related to it in the backtraces.
Could you please install the relevant debuginfo packages for Xwayland and post the output of "bt full" in gdb?
