Patch that fixes the segfault
Chromium can crash Xorg when the nouveau DRI driver is loaded. This is due to a
nullpointer dereference.
Archlinux bug (Xorg crash): <a href="https://bugs.archlinux.org/task/33994">https://bugs.archlinux.org/task/33994</a>
Fedora bug (Application crash, same cause):
<a href="https://bugzilla.redhat.com/show_bug.cgi?id=862466">https://bugzilla.redhat.com/show_bug.cgi?id=862466</a>
As suggested in the Fedora bug, <a href="show_bug.cgi?id=61947#c15">comment 15</a>, attached is a patch that fixes this
issue (confirmed on Archlinux). This is the same check the Intel DRI driver
does, so I think it's needed there.</pre>
