nvidia-settings crashed with SIGSEGV

Binary package hint: nvidia-settings

To store a new xorg.conf setup I run sudo nvidia-settings, and change from my laptop monitor to an external monitor. When I press "Save to xorg" it dumps:
VALIDATION ERROR: Data incomplete in file /etc/X11/xorg.conf.
Undefined Device "(null)" referenced by Screen "Default Screen".

Segmentation fault (core dumped)
