Summary0003709: gnome-control-center segmentation fault when trying to open User settings
Description

I am having a problematic issue with gnome-control-center that I can't seem to figure out after running apt-get dist-upgrade. I am able to open the settings as root user just fine. When I click on Users, nothing happens.I am running on Linux kali 4.7.0-kali1-amd64 0000001 SMP Debian 4.7.8-1kali1 (2016-10-24) x86_64 GNU/Linux.

dpkg --list gnome-control-center
Desired=Unknown/Install/Remove/Purge/Hold
| Status=Not/Inst/Conf-files/Unpacked/halF-conf/Half-inst/trig-aWait/Trig-pend

This is what I get in /var/log/syslog

Oct 27 21:00:09 kali kernel: [ 695.533180] gnome-control-c[1944]: segfault at 0 ip 00000000004c9a5d sp 00007fffae418480 error 4 in gnome-control-center[400000+394000]

I have tried running the command:
addr2line -e /usr/bin/gnome-control-center -fCi 0xC9A5D where 0xC9A5d is the offset into the object that was causing the problem and I get nothing.

I then ran:
addr2line -e /usr/bin/gnome-control-center -fCi 0x00000000004c9a5d and I get:
cc_universal_access_get_resource
??:?

Interesting...

I understand that the cause of this was that a user mode instruction resulted in a page fault. I have a couple gnome-control-center files of interest listed here:
/usr/share/bash-completion/completions/gnome-control-center
/usr/bin/gnome-control-center

I doubt that the issue is with the fist file listed since it is a bash script for tab completion.

I am unable to obtain a useful backtrace because I do not know how to get the debug packages. But anyways, here is the back trace I have obtained.

Sorry, this probably should be listed under a package bug.

The issue was resolved by manually going to the terminal and typing "sudo useradd temp". This allowed me to then access the gnome-control-center Users settings.

I still feel this is a bug though. It must have been segfaulting because it gnome-control-center was looking for a user when trying to Access the Users settings and there were none (but root).

I am also getting this error on a clean, updated install of Kali. Trying to open account settings results in

gnome-control-c[6141]: segfault at 0 ip 00000000004c9a5d sp 00007fff41aa6d10 error 4 in gnome-control-center[400000+394000]

I have the same error on a freshly installed and updated 2016.2

Adding another user with "useradd" does allow the "Users" window to be opened, however there is no access to the "root" user settings.

Attempting "useradd root" results in "useradd: user 'root' already exists" (perhaps obviously enough).

The segmentation fault in gnome control center was solved for some Ubuntu users by downgrading the gnome control center to its previous version, but I don't know how to go about that on this version of Kali Linux.

Something to consider:
The various settings windows can be accessed individually from the terminal by appending their name after "gnome-control-center" (e.g. "gnome-control-center keyboard" directly opens the keyboard settings window).

However, trying to do the same with the "users" window results in the error message " (gnome-control-center:1701): WARNING : Could not find settings panel "users""
