Today I got the coredump, but ubuntu-bug cannot upload it, saying
"ValueError ('not enough values to unpack (expected 2, got 1)',)". So I
use "ubuntu-bug xwayland" command, and attached the generated report.
This crash now seems only happens when the system is under load for some
time (in my case high cpu usage).
gdb stacktrace of this coredump, if anything helpful:
Reading symbols from Xwayland...Reading symbols from
/usr/lib/debug/.build-id/65/efba1189e8c1122d2e74c13bf7e54825c3e367.debug...done.

Bug description:
Went to log into my fairly newly upgraded ubuntu artful system today
but was presented with a new login instead of a login with all my
applications running, similar to #1728474 (
https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1728474 ),
only I didn't have to Ctrl-Alt-F1 to get a new login, I was presented
with one when I came to log in in the morning.
syslog gives a clue:

This, followed by everything that was running failing to various
degrees of cleanness.
