Title:
crash: unable to handle kernel NULL pointer dereference at (null)
Status in “xserver-xorg-video-nouveau” package in Ubuntu:
New
Bug description:
When using the program Hugin to stitch photos together, X/nouveau/linux
crashed. It crashed when it was loading the preview of the photos (which uses
3D?). I used Unity.
I got a backtrace (like on a tty), but the mouse still moved. Keyboard didn't
work anymore but I could SSH into the computer.
I made a bug report with ubuntu-bug (attached) and made two photos of both
sides of the screen with the crash report.
I've had such a crash before, that was probably the same bug. I think
that was while revealing the Unity launcher.

I have installed xserver-xorg-{core,video-nouveau}-dbg, so if it
happens again, I can post a better backtrace.
