(- off topic slightly.
It would be good it the gnome gitlab issue tracker could be added to launchpad 
as a valid 'location' to track upstream gnome bugs rather than the current of 
just bugzilla..

I have to go out, guess could file upstream bug tonight if no one does.. Seems 
best place is gitlab? https://gitlab.gnome.org/GNOME/gnome-shell/issues
The commit allowing this seems to be,
https://github.com/GNOME/gnome-shell/commit/cb4252e888c651c5a11fa0cb4c330e9351d61f1b

(- confirmed here by reverting that commit to latest ubuntu gnome-shell
source

Thank you for taking the time to report this bug and helping to make
Ubuntu better. The issue you are reporting is an upstream one and it
would be nice if somebody having it could send the bug to the developers
of the software by following the instructions at
https://wiki.ubuntu.com/Bugs/Upstream/GNOME. If you have done so, please
tell us the number of the upstream bug (or the link), so we can add a
bugwatch that will inform us about its status. Thanks in advance.

[Bug 1765353] Re: gnome-control-center crashed with SIGSEGV in acquire_cb() from g_simple_async_result_complete()

[Doug McMahon]

Ok but then you'd need to add/address gnome-software, software-
properties-gtk, synaptic, gnome-disk-utility, ect. as any & all of them
will cause/experience the same issue, sans a segfault.

As soon as 1 app that calls a pkexec auth dialog is canceled then no other app 
can use pkexec auth until gnome-shell is restarted.
As mentioned this does not happen in prior version of gnome-shell.

None of the other apps 'crash', they can however get an unresponsive window or 
in the case of gnome-software (ubuntu-software) it'll just endlessly show 
installing.
There's half a dozen test cases to see this that don't involve g-c-c at all.

[Daniel van Vugt]

The trigger may be in gnome-shell, but it would be poor engineering to
declare a crash in one process as fixed by modifying another.

So any proper fix should also include changes to gnome-control-center to
ensure crashing is impossible (even with a faulty gnome-shell).

[Doug McMahon]

Not sure why gnome-shell was removed as clearly that's were the issue is.
G-c-c may be the only apt actually crashing but this affects any apt that calls 
a pkexec Auth dialog. 
Easy examples are software & updates > change something, cancel the auth dialog 
or synaptic > cancel on the auth.
