Xwayland crashed with SIGABRT in OsAbort()

[Brian Neltner]

I previously had bug https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1724557 which causes the desktop to hard crash when the monitor is turned on, related to gnome-shell and mutter.

That bug hasn't reported anything to /var/crash lately, but the behavior has stayed the same for me. If I turn my monitor off while playing music, when I turn it back on the desktop session has crashed and I have to start a new session. The music makes pretty clear that it is specifically related to the monitor turning on.

Now the crash report coinciding with the crash of the desktop session with the correct timestamp is this one. I am not sure if the two bugs are connected, so I am reporting it as a new bug.
