Bug description:
  ==== 10.10 SRU ====
  I'm requesting a backported fix for 10.10's gnome-power-manager based on the menu leak I found in 11.04.  It's a simple one-line change, only affecting gnome-power-manager (rather than fixing root cause in libappindicator, because that potentially may adversely affect consumers that worked around it, though we know of none).

  gnome-power-manager is seemingly the worst offender, so it gets
  special treatment.  Test case right below.  Watch memory use for a
  bit.  It may go up for a few minutes, but then stabilizes.

  Debdiff to follow, it's already been uploaded to maverick-proposed.
  ===================

  TEST CASE: (at the beginning because it's a long post):
  1. Monitor the output of the command for a few hours
    $ watch -n1 'grep heap -A11 /proc/$( pidof gnome-power-manager )/smaps'

  VERIFICATION SUCCEEDED:
  - Memory usage is stable over time

  DESCRIPTION:
  Binary package hint: gnome-power-manager

  gnome-power-manager (2.30.0-0ubuntu1) seems to have a memory leak my
  machine running Lucid.  I witnessed it using up to 120MB in the RES
  column according to "top".  My machine is 64 bit and is connected to a
  APC uninterruptible power supply.  I haven't yet tried unplugging it
  to see if the UPS is somehow related to this problem.  Another person
  reported a similar problem in bug #196688 comment 25.  Opening a new
  bug seemed like a good idea since that bug was fixed 2 years ago.

  Here is some information for what gnome-power-manager looks like after running for a long period of time (from  /proc/`pidof gnome-power-manager`/smaps):
  0147b000-08810000 rw-p 00000000 00:00 0                                  [heap]
  Size:             118356 kB
  Rss:              118188 kB

  Swap:                  0 kB
  KernelPageSize:        4 kB
  MMUPageSize:           4 kB

  I rebooted my machine and let it sit at the login screen.  I logged via ssh and found that gnome-power-manager was using the following:
  01f6e000-02075000 rw-p 00000000 00:00 0                                  [heap]

  Rss:                 944 kB

  Private_Clean:         0 kB

  Swap:                  0 kB
  KernelPageSize:        4 kB
  MMUPageSize:           4 kB

  I logged out of my ssh session and didn't touch the machine until 5 and 1/2 hours later---and I logged in again remotely with ssh to check on gnome-power-manager and found:
  01f6e000-02e5d000 rw-p 00000000 00:00 0                                  [heap]
