Public bug reported:
I don't have any Thunderbolt devices so I masked the unused the
bolt.service. This causes problem with gnome-control-center.
Steps to reproduce:
1) launch gnome-control-center
$ gnome-control-center
2) navigate to Thunderbolt section
go to Devices, then Thunderbolt and close gnome-control-center
3) mask bold.service
$ sudo systemctl stop bolt.service
$ sudo systemctl mask bolt.service
4) re-launch gnome-control-center
$ gnome-control-center
