tracker dep will soon be dropped
This is just to inform everyone that I do realize that a hard dependency on tracker is not the way to go and this is just a temporary measure. I am writing a gstreamer/gio based metadata extractor as we speak. Although I'll try my best to get this done before GUADEC at least, it might take longer since I do this on my spare-time (something I don't have in abundance). Disclaimer: I am not against tracker and I *will* keep the current tracker-based media source (as a plugin), though i might need to drop that as a temporary measure for while until i get the plugin system implemented.
