This is not just about the 100% CPU usage. Unity-panel-service increases memory usage by 2MB every second you leave the sound menu open after you pause rhythmbox. This is in addition to the, in my case, 75% to 85% CPU usage.
I stopped the music and left the computer for a while with the soundmenu opened. When I came back unity-panel-service using 1.6 GB of RAM. I had to kill it from a virtual terminal to make the system responsive again.
Here's how I reproduce it.
1) Open system monitor or top and sort by memory usage
2) Open soundmenu and start Rhythmbox from there.
3) Press play in the soundmenu to start a song
4) Press pause in the soundmenu
Now while soundmenu is open, unity-panel-service memory usage increases at a 2MB per second rate and it never goes down, not even closing rhythmbox or soundmenu.
