Removing (purging) avahi-daemon and rebooting does not trigger this bug anymore and gnome-control-senter starts up fine. Selecting "Sharing" crashes gnome-control-center and the bug happens again. Using an englisch locale does not help, the "error word" is still german, but "Speicherzugriffsfehler" means "segmentation fault". Using G_MESSAGES_DEBUG=all gives me a better description: foo@bar:~$ G_MESSAGES_DEBUG=all gnome-control-center -v (gnome-control-center:3226): cc-object-storage-DEBUG: 19:00:55.068: Initializing object storage (gnome-control-center:3226): Gtk-DEBUG: 19:00:55.068: Connecting to session manager (gnome-control-center:3226): network-cc-panel-DEBUG: 19:00:55.086: Monitoring NetworkManager for Wi-Fi devices (gnome-control-center:3226): cc-object-storage-DEBUG: 19:00:55.105: Adding object NMClient (CcObjectStorage::nm-client → 0x5590b5dc3d00) to the storage (gnome-control-center:3226): network-cc-panel-DEBUG: 19:00:55.105: Wi-Fi panel visible: no (gnome-control-center:3226): wacom-cc-panel-DEBUG: 19:00:55.106: Wacom panel visible: no ** (gnome-control-center:3226): DEBUG: 19:00:55.115: Not allowed to change the hostname (gnome-control-center:3226): cc-window-DEBUG: 19:00:55.272: Time to open panel 'Freigabe': 0,160000s 19:00:55.0332 sharing-cc-panel: DEBUG: Error calling GetHostNameFqdn: GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name org.freedesktop.Avahi was not provided by any .service files Speicherzugriffsfehler 'Freigabe' means 'Sharing' I don't know where I can get the package with debugging symbols for gnome-control-center. gdb just shows "Reading symbols from gnome-control-center...(no debugging symbols found)...done." and there is no gnome-control-center-dbg package (or any gnome related package) At least there is some more info with G_MESSAGES_DEBUG=all, so this may help a little. Thank you for your time and work.
