I (finally) managed to find one of the sources for this problem. It
looks like our "sotware-center.css" file causes some css that has a
memory leak to be drawn.
To reproduce:
- open a tool like htop and sort by memory usage
- run software-center and scroll around the lobby
- watch the htop RES column for software-center increase just from scrolling
Note that this does not increase any python visible object count, just the RES
data.
When the software-center.css is disabled this stops leaking memory.
I will try to build a stock Gtk test case next.

Title:
Software center page changes add between 2 and 6 meg to the memory
size
Status in “software-center” package in Ubuntu:
Confirmed
Bug description:
Prep:
Grab myutils from lp:~davmor2/+junk/testscripts
From xpresser/xp_trial run import myutils
Run it against software center with myutils.statinfo('software-center')
Steps:
1. Open USC give it about 20secs it will level out at about 170 meg
2. Click on an app run myutils.statinfo('software-center')
3. Click on All Software and run myutils.statinfo('software-center')
4. Click on a different app and run myutils.statinfo('software-center')
5. Click on All Software and run myutils.statinfo('software-center')
6. Click on the same app again and run myutils.statinfo('software-center')
My assumption is that the webkit display isn't dropping info once the
page is no longer displayed.
This is good for speed returning to a page but is drastically
increasing the memory footprint of USC when searching through a
selection of apps for a new user not familiar with the application
names.
