Actually those assertions might not be fatal. Such is the way with glib
and friends.
So let's call this a duplicate of the first issue: bug 1505409
Work is underway upstream to remove this dependency of gnome-shell on
Xwayland, which will solve the problem. But it's not finished, or at
least not enabled by default yet.
** This bug has been marked a duplicate of bug 1505409
gnome-shell crashed with SIGTRAP in x_io_error() from _XIOError() from
_XEventsQueued() from XPending() from gdk_check_xpending() ["Connection to
xwayland lost"]

Title:
gnome crashes when using qemu display
Status in gnome-shell package in Ubuntu:
Incomplete
Bug description:
Using the qemu vga display under gnome is reliably causing gnome to
crash on my laptop. I've seen this when using libvirt and also when
invoking qemu from the command line. I've tried several display
options for qemu:
-vga qxl
-vga virtio
-display gtk
All result in the crash. No crash report is appearing in /var/crash
after this happens, but I checked dmesg the last time and found this:
[15078.446564] gnome-shell[10327]: segfault at 8 ip 00007f4c53c794af
sp 00007ffd7eb03e90 error 4 in libmutter-cogl-1.so[7f4c53c14000+a5000]
The crash usually doesn't happen right away. Sometimes it happens a
few seconds after the display is opened, other times it's happened
when I've moved to another window and then select the qemu display
using Alt-Tab.
