I've noticed that rhythmbox-scope for unity-hud's music-lens is taking something above 18% of my memory all the time without doing anything useful.
Actually using it for searching music doesn't change the consumption rate in any way. It's rock steady at 18,xx %, thus making it the worst memory eater on my entire system.
I'm using a Samsung R710 notebook with 4GB ram (which should be enough IMHO) with Ubuntu 12.04 LTS.
Any suggestions on how to lower this memory usage other than uninstalling the music-lens or rhythmbox-scope would be very much appreciated.
Thanks in advance for any useful answer!
BTW: Rhythmbox itself is quite memory hungry as well, making it choke every now and then on title change. Perhaps this is somehow related?
