The crash appears when choosing "Details" in the list to the left of
the Gnome Control Center. When doing so, "Details" becomes the last
choosen panel, and is opened automatically when starting gnome-control-
center again. This then causes the crash to occur again, this time
immediately.

So, knowing that, I have a gnome-control-center which works, except for
the menu item "Details", which causes a crash.

The issue looks like the same as 
https://gitlab.gnome.org/GNOME/gnome-control-center/issues/285

Looking at the Depends attachement,

libglib2.0-0 2.60.0-1ubuntu0.1~ubuntu18.04.1~ppa1 [origin: unknown]

That's likely you issue, you are using an outdated libglib from a ppa
which doesn't include the fix for that issue
-----snip-----  

So now I'm wondering if I can install a newer version of libglib2.0, in
order to fix this. My system is bionic 18.04.3 LTS. My version of that
library is:

desktop ~ $ apt-show-versions libglib2.0-0 
libglib2.0-0:amd64 2.60.0-1ubuntu0.1~ubuntu18.04.1~ppa1 newer than
version in archive

The following page on packages.ubuntu.com lists available versions of
libglib2.0:

https://packages.ubuntu.com/search?keywords=libglib2.0&searchon=names&suite=all&section=all

There the following versions (disco and eoan), which are newer than my
version, are mentioned:

(my version):  2.60.0-1ubuntu0.1~ubuntu18.04.1~ppa1
disco-updates: 2.60.4-0ubuntu0.19.04.1
eoan:          2.62.0-1

Is it possible to use one of those, or would I nuke my system, if i
tried?
