Hi,
i switched my login shell back to bash (chsh -s /bin/bash) and i was not
able to reproduce the issue in ~30 resume/suspend cycles. This is still
no valid statistic but is it possible that zsh as login shell can
segfault mutter? Of course, I will report if it occurs!
ubuntu-bug still has the problem with the old crash file, probably since
it wrongly generated or?
Thanks and sry for this non-default setup.

Additionally, i have ~100MB "core" file in my home directory.
I tried to report the created _usr_bin_gnome-shell.1000.crash file
using the workaround from
https://bugs.launchpad.net/ubuntu/+source/apport/+bug/994921 and
ubuntu-bug. However, i get the error: "The problem cannot be reported:
Invalid core dump: BFD: warning /tmp/apport_core_ersfx7ym is
truncated: expected core file size >= 846290944, found: 216288"
reporting the corresponding _usr_bin_Xwayland.1000.crash file forwards
me to https://bugs.launchpad.net/ubuntu/+source/xorg-
server/+bug/1731911. But this only seems to indicate that Xwayland
crashes since mutter has crashed.
This error only occurs when using the wayland and not in the xorg
session.
I am running 4.16.10 mainline kernel due to some driver issues with my
laptop (thinkpad x1 carbon gen6) but this also occurs when using the
4.15 kernel and with and without loading the guc firmware.
Thanks!
