Today my brothers, (9 and 12), told me of a similar story. They were listening to iTunes and burning music cds when a screen popped up in different languages tell them to restart.
They immediately began arguing with one another about whose fault it was and then they called me.
At first I was shocked, but then I remembered reading about it here. I really had no clue about what it might be.
Thanks to you guys I now have some kind of idea. I'll have to check into the panic.log.
Thanks again MacOSX.com community!
