Tracker appears to spill raw indexed contents into journalctl, which in turn makes the log quite a pain to read if you want to find actually INTERESTING stuff since it's, you know, the system log.

Example:

In case this is actually a distribution configuration error of some sort: I'm using Gnome 3 as shipped by Fedora 21.
