I got it finally with some proper JS stacktrace, in my case it was an

[Daniel van Vugt]

We know. There are 830 reports of this crash from 18.04 right now:
https://errors.ubuntu.com/problem/811164cadd3e9e891f9e2d439bda59925f91a62c

And globally this is the 9th most common gnome-shell crash for 18.04 (or
6th if you look at just the past month).

[Bug 1759621] Re: gnome-shell crashed with SIGSEGV in g_type_check_instance_cast() from st_label_set_text() from ffi_call_unix64()

[hackel]

Sadly this is still happening to me on 18.04 as well.  Every single time
I resume my machine from suspend.  And it's not just that gnome-shell
crashes, but I have to sit for a good 2-3 minutes while apport does its
thing, while the machine is completely frozen from a UI perspective.
This is such a huge usability issue!  I still suspect it is being caused
by some particular combination of gnome-shell extensions that are
installed.  I've tried (unsuccessfully) to pin down which one it is, but
it never seems to work, leading me to believe it must be a combination.

I've attached my journalctl output, captured from the moment I resumed
my machine.  Really hope we can get to the bottom of this!

Not sure if this issue is related but since I upgrade to the last daily
update I am not able to click with my trackpad or connected mouse. When
I suspend the laptop, I can use the keyboard to open a terminal.

Gnome-shell is reporting this bug since this problem appears.

I am using an XPS 13 - 9370
