Application: kwin (4.5.1 (KDE 4.5.1))
KDE Platform Version: 4.5.1 (KDE 4.5.1)
Qt Version: 4.7.0
Operating System: Linux 2.6.32-24-generic i686
Distribution: Ubuntu 10.04.1 LTS

-- Information about the crash:
- What I was doing when the application crashed:

* a few desktops with Google Chrome windows open
* a few konsole windows open
* Amarok running
* Lots of software in the background (ie: apache & mysql.)

This crash is on a very old (ie: approx. 8 years) notebook. It was state-of-the-art hardware at the time but is still running the original hard disk and only 1gb of ram. I'm guessing it crashes more often due to issues related to memory allocation.

Thanks,
Sam.
(p.s. Loving 4.5!)
