-- Information about the crash:
I was loading software updates and it did ka-boom :(

The task bar disappeared as well as my custom wallpaper. They automatically returned and I got a message asking me if I wanted to file an automatic bug report.

CPU: intel e6300 core 2 duo @1.86 Ghz
RAM: 3GB DDR2-533

The crash does not seem to be reproducible.
