Bug Description

* Impact

gnome-conrol-centrel segfaults sometime when trying to open in-existing panels (can happen under other desktop with valid names since depending of the OnlyShowIn some panels might not be listed)

* Test case
- call "gnome-control-center invalidname", it shouldn't hit a segfault

it's also worth checking the error tracker reports, they should stop, also on
https://errors.ubuntu.com/problem/73835fe215683e2f5f85df231eb2750a57e96c65

* Regression potential
Check that no panel is missing and that you can open directly subpanel by calling "gnome-control-center <name>
