[Tracker] No metadata in search results

[Brian Davis <brian william davis gmail com>]

Jamie, it's great to have you back. Things picked up in my life as
well and Hum development stagnated a bit. I was cleaning up some bugs
when I realized that the metadata issue I was whining about never
seemed to go away for me. Any calls I make to "tracker_metadata_get()"
return pointers to empty arrays. 

I'd love to find out that I'm misusing the API, but the trackerd logs
appear to be properly extracting and returning the correct metadata.

You had mentioned a few months ago that this was a known issue. Is
there a fix in the pipeline?
