Tracker is started in your session startup, not via systemctl and you
can disable it if you want. In my case, I have it start in my session.
I am running 64-bit F17 using XFCE and have no issues with it (tracker
version 0.12.10). If I want to disable it I'd go to

     Applications->Settings->Settings Manager->Session and Startup

select the "Application Autostart" tab and uncheck the tracker-related
items.

Again, I have no issues and I'm running 64-bit F17 on four machines.
