[Bug 1199877] Re: unity-panel-service pegs one of my CPUs at 100%

 

Simple reproducer that shows a leak in unity-panel-service (there may be
other scenarios that cause a leak too):

1) Open a terminal and watch the RSS size of the unity-panel-service process:
watch -n 0.5 ps -o rss= `pgrep unity-panel`
2) The value reported should stabilize
3) Launch gedit. Observe the value goes up a bit
4) Quit gedit. Observe that the value does not go down
5) Launch gedit. Observe that the value goes up again

Bug description:
  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.
