Not a fix, but a workaround: Each time app_indicator_set_menu() is
called, we leak by 200k. so, I reduced the number of times it gets
called. (Currently called any time a device is updated, which seems to
happen every 30 seconds. Devices are updated even if nothing has
changed.)

I'm rather novice, so I've probably fudged something else up by doing
this. It works for me (desktop, wireless mouse being the only battery
indicator I have) I couldn't make heads or tails of the actual leak
itself, though.

The attached patch has been applied to package, and uploaded to my ppa:aaron-haviland/ppa for Maverick.
I've also applied it to the Lucid package and uploaded, but I don't have a lucid system to test it on.

After running for 2 hours, according to /proc/pid/smaps Rss has only
increased by 240kB

Bug description:
  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]

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]

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]
