Memory leak in Gimp 2.8.6

[jondecker76]

I just upgraded from 13.10 from 13.04. My wife is a professional photographer and relies on Gimp for the brunt of her editing.

After the upgrade, the system would routinely slow to a crawl while she is working. This is on a modern system with 4GB of RAM.

We started watching memory usage in Top while she edited to try to see what the problem was. Every time a new filter, plugin, tool, etc is used - the used memory goes up and the free memory goes down. When the tool/filter/plugin is finished, this memory is never freed back up. This continues all the way until we are using swap space and things then really slow to a crawl. Closing Gimp frees all of the memory, then it will work fine again for a while during use until all the free memory leaks over again, at which time she must save her work, close gimp and start again.

This could be related to: https://bugs.launchpad.net/ubuntu/+source/unity/+bug/1199877?comments=all and not a gimp bug at all...

I think its triggering a bug in unitu-panel-service where the actual memory leak is.

Is there a way to profile and determine where the leak is coming from?

I just ran valgrind via:

[code]
sudo killall unity-panel-service && valgrind --leak-check=yes --log-file=./valgrind.log /usr/lib/unity/unity-panel-service
[/code]

I'm attaching the valgrind log for just a few seconds of running gimp.

This report can be closed, as it's obviously a bug in Unity and not Gimp.

I tried Gimp while Choosing Gnome and Cinnamon at login and everything worked great as it should.
