Bug#753919: gnome-control-center: unlock button does nothing

[Jérémy Lal]

Package: gnome-control-center
Version: 1:3.18.2-1
Followup-For: Bug #753919

Dear Maintainer,

I'm seeing the same problem here with printer or user settings.
This appears in journalctl

nov. 28 09:38:15 imac gnome-session[2584]: AuthenticationDialog<.performAuthentication at resource:///org/gnome/shell/ui/components/polkitAgent.js:224
nov. 28 09:38:15 imac gnome-session[2584]: wrapper at resource:///org/gnome/gjs/modules/lang.js:178

and this appears when launching gnome-control-center, going to user settings, click unlock,
then close gnome-control-center window:

(gnome-control-center:6383): GLib-GIO-CRITICAL **: g_permission_acquire_finish: assertion 'G_IS_PERMISSION (permission)' failed
Erreur de segmentation

Regards,
Jérémy
