Maybe nobody has filed in bug against it in bugzilla.gnome.org, but the upstream translation of Rhythmbox is definitely incomplete. If you take a look at
and search for "Pre_vious" you can see that it's marked as fuzzy and therefore untranslated. That's exactly the string displayed in the system tray. I am just working on updating the upstream translation (I also contribute to the GNOME German Translator Team).
