Here's my system info from uname -a:
Linux fu457 4.6.0-kali1-amd64 #1 SMP Debian 4.6.4-1kali1 (2016-07-21) x86_64 GNU/Linux
GNOME Shell 3.21.91
Now, when I go to 'Settings' and click on 'Keyboard' to add a custom shortcut key, the 'Keyboard' setting window will not open. It will flash a second or two in the taskbar (topbar) and exit immediately.
