"Session and Startup" does not disable tracker*

Steps to reproduce

1. Open "Session and Startup" (xfce4-session-settings)
2. Disable...
   • "Tracker File System Miner ..."
   • "Tracker metadata Extractor ..."
   • "Tracker Store (....)"
3. Enable a way to figure out if they are run
   • I used: renaming executables usr/libexec/tracker*
4. Reboot system
5. Check /var/log/syslog: System tries to start the services ( if the executables are renamed, an error file not found will be shown)

Apparent problem

There are two entries for tracker*:

• $XDG_CONFIG_HOME/autostart ( more info: https://wiki.archlinux.org/index.php/XDG_Autostart )
• /usr/lib/systemd/user/tracker*.service

Session and Startup does not alter the files in /usr/lib/systemd/user/tracker*.service, but only in $XDG_CONFIG_HOME/autostart.

Workaround

Manually rename /usr/lib/systemd/user/tracker*.service to /usr/lib/systemd/user/tracker*.service.disabled
