Not so much CPU usage here, but leak is confirmed (I have the issue
since the release of 13.10 ...), at the end of they day memory usage
(according to top) is about 6-10% on a machine with 2Gbyte RAM. If I
kill the process, it relaunches and uses much less memory, below 1%, but
again it sightly increasing with time. So I have to kill it about some
times  within a day to be able to work without heavy swapping. However
as I've told, not so much CPU is consumed here, I have no problem with
that at least. 13.10 on x86 32 bit.

Bug description:
  Impact: high CPU/memory usage from unity-panel-service

  Test case:

  Open a large image in the GIMP and activate a lot of items from the
  global menu. Using shortcuts is enough and faster to reproduce this
  bug (I've always used Ctrl+A and Ctrl+Shift+A). Memory usage of unity-
  panel-service increases steadily and it uses a lot of CPU shortly
  after activating the menu items in a short time.

  Regression potential: check that the menus are stable/working as they
  should

  ---------
  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.
