This bug was fixed in the package gnome-control-center -

---------------
gnome-control-center (1:3.28.1-0ubuntu1.18.04.1) bionic; urgency=medium
* debian/patches/0001-shell-Don-t-set-per-panel-icon.patch,
debian/patches/0002-shell-Icon-name-helper-returns-symbolic-name.patch,
debian/patches/0003-thunderbolt-new-panel-for-device-management.patch,
debian/patches/0004-thunderbolt-move-to-the-Devices-page.patch:
- backport the new upstream "thunderbolt" panel (same patches as fedora
is using). Also change to not use per panel icons but just the
settings one, that's the right thing to do and avoid issues when
some panels like the thunderbolt one don't have a symbolic icon.
(lp: #1773378)
* debian/patches/git_select_panel.patch:
- "Only try to select an existing panel on startup",
otherwise it's possible to hit a segfault (lp: #1773382)
[ Andrea Azzarone ]
* debian/patches/git_invalid_dereferencing.patch:
- Avoid dereferencing invalid pointer (lp: #1759468)

gnome-control-center sometimes hits a segfault
* Test case
- Check if the e.u.c reports stop with the new version
or
- Open GNOME Control Center
- Go to Devices->Display panel
- Close the window
- Open GNOME Control Center again (in overview mode)
the settings should open without error
* Regression potential
check the panels can be opened without error and that switching between them
works as well
