Bug#855310: gnome-control-center segfaults in user applet when no (non-root) user exist

[Raphaël Hertzog]

Package: gnome-control-center
Version: 1:3.22.1-2
Severity: important
Tags: upstream patch
User: devel at kali.org
Usertags: origin-kali
Control: forwarded -1 https://bugzilla.gnome.org/show_bug.cgi?id=773673

The user applet will segfault when you try to open it and when you have no
non-system user on your machine... and if you want to open this applet
precisely to create a user, it's somewhat counter-productive.

This is unusual but it's the default situation that we have in Kali since
the live system only contains the root user by default. It would be nice
if we could get this fixed in Debian in stretch.

I submitted a tested patch upstream:
