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):

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:

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:
