gnome-control-center segmentation faults when launched
For some weeks now, maybe since upgrading to 21.04 (maybe earlier, not sure), gnome-control-center has been segfaulting every time I try to run it, right at start up. The gnome-control-center package version is 1:3.38.5-1ubuntu1.
Things I've tried:
sudo apt update; sudo apt dist-upgradesudo apt install --reinstall gnome-control-center- Clearing
~/.cache/gnome-control-centerand~/.config/gnome-control-center - Disabling all extensions
- Switching from Wayland to Xorg
Backtrace given by gdb /usr/bin/gnome-control-center core (edit: updated with more debug symbols):
Core was generated by `gnome-control-center'.
Program terminated with signal SIGSEGV, Segmentation fault.

Any pointers or ideas?
Can you try
$ gsettings reset-recursively org.gnome.desktop.wm.keybindings
and then reboot, to see if that helps your problem?
