[arch-general] Solutions to avoid strange gnome-control-center crash

[leoutation at gmx.fr]

Hi
Yesterday, i tested Gnome 3.32 for a friend. I would like to point out
that Gnome-control-center crashes. I discovered it was because of
Connman running.
Solution 1 : stop temporarily Connman
Solution 2 : replace Connman with Network-Manager
This bug has been reported upstream 6 months ago
