Bug Description
Binary package hint: gnome-system-
Just opening system monitor (not sure if it's always) causes one of my CPUs to go to 100% usage. The process Xorg is the one that actually has all the CPU usage but I guess it must be system-monitors fault.

dpkg -l | grep xorg-core
ii xserver-xorg-core 2:1.4.1~
$ dpkg -l | grep gnome-system
ii gnome-system-
I tried to find out what was going on and started a strace on the Xorg process and that completely locked upp my system. Tried to switch to a console with ctrl-alt-f1 but no success. Remotely connected to the system with SSH and found that the CPU usage was good and as soon as I killed -9 the strace process the system was OK again.

The system felt a bit slow so I logged out. This wasn't successful, only all icons any everything disappeared now only showing my background picture. I tried using the keyboard but nothing worked. I did a SSH to the machine and logged in without any problems. Noticed Xorg process taking 100% CPU. Also noted this in kern.log:

Tried to kill the Xorg process but wasn't successful, not even with -9. /etc/init.d/gdm stop was also useless. Managed to reboot it with ctrl-alt-delete.
