As I comment in Bugzilla: Testing latest Ubuntu 16.04 (development branch):
$ gnome-control-center --version unity-control-center 14.04.3 I cannot reproduce the bug and no warnings appears, so probably it is fixed at some point. The weird thing now, it is that the tool reports as unity controll center instead gnome control center and the version looks 14.04 instead 16.04, but thats probably a Ubuntu thing in downstream -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-control-center in Ubuntu. https://bugs.launchpad.net/bugs/1255525 Title: GLib-GIO-CRITICAL **: g_settings_get_value: assertion 'G_IS_SETTINGS (settings)' failed To manage notifications about this bug go to: https://bugs.launchpad.net/gnome-control-center/+bug/1255525/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
