That doesn't really give us anything to work with.

Does top/ksysgard show anything before it breaks?

After doing somme more research and testing it looks like its the known memory leak when a picture slideshow is being used as the desktop background.  After switching to a static image the behavior hasn't returned, switching back triggers the issue after a few hours.

I think there is another bug out there for this but I'm having trouble finding it.
