Xorg log.

Hello:

I'm on Debian testing with graphic stack from sid, this is:
xserver 1.7.4
mesa 7.7
linux 2.6.32
libdrm 2.4.17
radeon 6.12.4

01:00.0 VGA compatible controller [0300]: ATI Technologies Inc Mobility Radeon HD 3600 Series [1002:9598]

I was on KDE 4.3.4 with desktop effects on. I added a lot of downloads to kget and the plasma notifier opened a lot of notifications. As I have the notifier in the left side of screen, in this case the notifications would have overflown the screen height, so they couldn't have been seen. Anyways, I couldn't see them becuase xserver crashed with this backtrace:

I guess it's related to trying to draw something out of the screen bounds.
