gnome crashes when opening gnome-control-center

[Chris Poliquin]

Version information:
  Ubuntu Release: Ubuntu 18.10
  xserver-xorg-video-nouveau: 1:1.0.15-3
  gnome-control-center: 3.30.2

Expected Behavior:
Launching gnome-control-center should show Ubuntu settings.

What Happens:
Launching gnome-control-center causes gnome to crash, resulting in user being logged out and returned to login screen.

Further Information:
I ran `gnome-control-center -v > out.log 2>&1&` to investigate and get the following in the log...

    nvc0_screen_create:983 - Error allocating PGRAPH context for M2MF: -16
    XIO: fatal IO error 11 (Resource temporarily unavailable) on X server ":0"
          after 11 requests (11 known processed) with 0 events remaining.

Disabling gnome extensions does not help.
Switching to proprietary drivers resolves the issue.
