Just going about my business on Ubuntu Raring amd64 on an x230 and I heard the fan kick into action. top showed me that unity-panel-service was consuming all the free cycles on one of my CPUs. I killed it before my machine overheated, so I didn't attach a debugger to see why it was totally pegging out a CPU.
I'm not sure if this adds any context, but I was using a LibreOffice spreadsheet and I could not insert a table because the menu had lost it's mind, and then I observed the overly loaded CPU a very short while after that.
