I don't think that Rhythmbox copies music files from MP3-players if the user hasn't told it to do so.
What you saw was Rhythmbox scanning your Music folder. It is default behaviour of Rhythmbox to watch that directory and make sure all music files in that directory are in its music library. It doesn't move or remove or import any music files, it just adds files in your Music folder to the library, so you can play the songs through Rhythmbox.
As far as I know, you need to grep the actual dbus-session of the machine that runs rythmbox. This is kind of tricky.
I have installed a script at my server, which is run after boot automatically, and which saves the current dbus-address to a file in my homedir.
If I ssh to the machine later, I can just grep the session-adress from there.
I: Script to store dbus adress:
name it "Get.Dbus.sh" and save it somewhere to your disk. Give it the following content:
set | grep DBUS_SESSION_BUS_ADDRESS > ~/.DBUS_temp
make it executable and add it to your start-items
II: Script to grep the current session:
name it "Run.DBus.sh" and save it in e.g. /usr/local/bin/
Give it the following content:
source /home/YOUR_USERNAME/.DBUS_temp
export DBUS_SESSION_BUS_ADDRESS
$*
don't forget to make it executable
III: ssh to your machine and start the rhythmbox-client as follows:
Run.DBus.sh rhythmbox-client
This works here!

Rhythmbox 0.13.3 is older than the current packaged version. Launchpad may be missing release information for the main series or this package is linked to the wrong Rhythmbox series.
