You have been subscribed to a public bug:

xserver-xorg-video-intel version:   2.8.0-0u
xserver-xorg-core version:  1.6.3-1u

X crashes when using some applications as Google Earth.

The crash is very easy to reproduce, as I noticed recently:
1. Open Kolourpaint (KDE drawing program), and select the pen tool.
2. Start drawing some doodle by pressing the left button of your mouse
   _without releasing it_ for at least 30 secs (keep the cursor moving).
3. X crashes.

 
here's a backtrace found in /var/log/kdm.log
