Title:
gnome-control-center crashed with SIGSEGV in actualize_printers_list()
Status in gnome-control-center package in Ubuntu:
Fix Released
Bug description:
Test Case
=========
From Ubuntu 18.04, click the top right of the screen to open the system
status menu.
Click the gear button at the bottom to open the Settings app.
In the Settings app, click Devices > Printers.
Close the Settings app and then use the system status menu to re-open
Settings.
Navigate to the Printers panel.
gnome-control-center crashes
Other Info
==========
I can reproduce the crash in Debian Buster also.
This is also reproducible by opening the Settings app from the
Activities Overview.
This is not reproducible by running gnome-control-center from the
command line.
It's also odd that running gnome-control-center will always open the
last opened panel (this is a GNOME 3.28 feature), but running it from
either the Activities Overview or from the system status menu will
only open the last opened panel if it is not in the Details or Devices
submenus.
