Kernel log from boot. The issue occurs at 19:02.

Hi,
First, sorry if I make mistakes, English isn't my native language.

I'm experiencing an annoying issue since I use Nouveau driver (which I keep
up-to-date).
Sometimes, when I'm playing a video, my screen completely freezes. I can still
move the cursor (which keeps the same appearance) but I can't do anything else.
Ctrl-Alt-Backspace doesn't restart X, and Ctrl-Alt-Fn doesn't bring me to a
console. The sound stops too. I have to manually shutdown the computer.
This bug occurs whith any player (mplayer, vlc...). It doesn't occur with
videos embedded in a Flash plugin. I would say this happens half the time,
often during the first seconds.

I'm using Debian Sid for amd64. My graphic card is a GeForce 8200.
I have RandR enabled and two monitors.

I attach my kernel log. The issue occurs at 19:02. These are the most useful
lines :
