Notes from irc log;

(15:01:52) tedg: klattimer, Yeah, so ayan has a small GTK program that creates and destroys menus and causes a leak in GTK...
(15:03:37) tedg: I was talking to hughsie a while back and he was saying it depends on the battery firmware how often it updates.
(15:03:51) tedg: Which probably explains the variation of folks reporting things on the bug.
(15:06:12) tedg: I wonder if there's something of the wrong type so that hashtable isn't getting free'd.
(15:06:28) tedg: In theory dbus-glib should do that... but I don't have a huge amount of faith in it.
(15:06:52) tedg: klattimer, The last entry in the valgrind log.  For properties_copy
(15:07:04) tedg: It allocated a hashtable which get's passed to dbus-glib.
(15:08:42) tedg: No, I think that serialze_menu item has a leak of that hashtable....
(15:08:47) tedg: Uhg.

So there are gtkmenu leaks, and libdbusmenu-glib leaks - best thing to
do is fix libdbusmenu-glib and upstream the result of ayan's tests to a
gtkmenu bug.

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]
