This crash is now fixed in Ubuntu 18.04. But I'll leave the gnome-shell
task open for a while to help people and bots find the bug more easily.

I feel conflicted about letting gnome-shell just exit. It will result in some
people logging bug reports that we can't diagnose, but those will be orders of
magnitude fewer than what we see now.
So short term for 18.04, it's a good idea. Slightly beyond that, it's
going to keep hurting us
It looks like upstream has a "fix" coming:
https://gitlab.gnome.org/GNOME/mutter/commit/2d80fd02e76bbe17dc52072299dda92ab88c99c0
Although that will just stop the crash reports from occurring and not
fix the root cause. That may be all we need for now...

Actually (a) might be explained if Xwayland is restarting itself on some
X error. But in Xorg terms it can restart the server anew without
exiting. So gnome-shell would see this as a crash while the Xwayland
process stays running.

Update: Now we've had the fix for bug 1746874 released in 18.04 for a
couple of weeks we should be able to see some correlation between gnome-
shell and Xwayland crashes, if there's any at all.
But we don't see any correlation. In the past week, Ubuntu 18.04 has hit

I have now reopened bug 1732878. So hopefully the bots will find that
one and I won't have to deduplicate them by hand any more.
Bug 1732878 is still really a duplicate of this one for the sake of
fixes. Just that the stacktrace changed slightly in 18.04's
3.26.2-0ubuntu1.

Bug 1746653 (private) mentions that Xwayland is dumping core (just

for a lot of people... we wouldn't get the crash reports we need.

I think we might need to split this bug in two, just for the sake of
automation.
In 18.04 the stack trace for this crash is a bit different. So our
robots don't notice it's the same bug as this. It might pay to un-
duplicate one of the newer forms, just so the robots can find it and
will stop
Happy 2018.
Now we've got Xwayland leaving core files when it crashes (fixed in
mutter 3.26.2), we still see very few Xwayland crashes. Too few to
account for most (90%+) of the instances of this bug...

Nicolás,
Yes please. In particular please try to report crashes using the crash files
left in /var/crash/ using this command:
ubuntu-bug /var/crash/YOURFILE.crash
or if that fails then:

Ok, Daniel, I understand. Should I file a specific bug about the
notification-related crash? There are a lot of bug reports with gnome-shell
crashes and some of them are probably related to the notifications, but i
don't know how to figure out which one is the one I am having.
El jue., 9 de nov.
It failed to hold true on day 2 anyway, as today the session didn't
survive the overnight sleep. But in any case I re-checked the bug of
mine that was marked a duplicate of this one, and saw as it was during
one of my brief try-outs with wayland, is irrelevant to my current
gnome-session woes, as
This bug is a catch-all bug. If Xwayland crashes for any reason it will
trigger gnome-shell death either in this bug or as bug 1556601.
While we appreciate everyone's efforts in diagnosing problems, in this
particular case the issue is already understood and doesn't need much
more comment.

Another follow up about this bug: after some more crashes I am realizing

starting to play a playlist on Spotify or changing the song. Gnome-shell

I think I have found I way to reproduce the crash of gnome-shell, at

a playlist so it shuffle-plays results in gnome-shell crashing and
recovering a couple of seconds later.

So, this definitely isn't a "fix", but it resolved the problem for me
(at least so-far). I simply dpkg-reconfigured over to another DN
temporarily, rebooted, then swapped back to GDM3 and it went away. Less
of a fix more of a band aid.

At least in my case, I think that the sensible approach is to make

Just for the sake of adding a comment too... I am getting this in the following
situation. I hope the description is correct.
1) I change the display set-up on my laptop slightly too fast, e.g. close the
lid, re-open, re-close (I did that quite a bit recently trying to work out bug
patterns).
Come to think of it, fixing bug 1724185 might also stop this and bug
1556601 from happening (most of the time, not all the time).
At the moment when gnome-shell/mutter shuts down, Xwayland doesn't cope
well and may silently crash, which in turn is caught by gnome-shell and
gnome-shell crashes
Here's a fix that will help us make rapid progress:

While this bug is the top gnome-shell crasher by far, it's actually not
what should be fixed first. What we should fix first are the top
Xwayland crashes that are triggering this bug.
Upstream would like to make gnome-shell more independent of Xwayland so
that Xwayland crashes don't also bring

Daniel, I think there are a lot of crashes that are never reported
because apport didn't work (maybe it still doesn't) in the Wayland

Weirdly there are practically no crashes reported for Xwayland:

This makes me suspect that gnome-shell might be managing the Xwayland
process and possibly hiding its crashes (including the root cause of
this bug) from errors.ubuntu.com.

In theory if the problem is Xwayland/Xorg going away then we could see a
