tracker does not "establish connection"

[Julian Brelsford]

Binary package hint: tracker

I ran "tracker-stats" in terminal and got this:
//////
Could not establish a connection to Tracker: GDBus.Error:org.freedesktop.DBus.Error.NoReply: Message did not receive a reply (timeout by message bus)
//////
When trying to use tracker to find files, its "working" animation (a bunch of little lines arranged in a spinning circle) runs indefinitely and no results are found.
