That bug has been opened on https://launchpad.net/distros/ubuntu/+source/gnome-media/+bug/44629

"I was looking at a system today where the virtual memory usage of gnome-cd was over 700MB. It seems this program leaks over 100kB each minute.

How I assessed this on my own machine:

1) With no cd in the computer, launch "gnome-cd". Just let it sit there.

2) In a terminal, run the following pipeline:

  while true; do time=$(date +%T) ; ps --no-headers --format "$time %z" $(pgrep gnome-cd); sleep 60; done

This will print the virtual memory usage of gnome-cd each minute with a timestamp. You can exit this command with Ctrl-C.

By the way, the particular version I have is gnome-media-2.14.0-0ubuntu2."
