Yes (for me it is in /usr/lib/tracker/tracker-extract). Starting this
manually then the file does get indexed, and found in subsequent
searches.

Not as far as I can tell.

Yes - this file is in place and points correctly
to /usr/lib/tracker/tracker-extract




As another test I killed my tracker-store and tracker-miner-fs process,
and then just restarted tracker-miner-fs. This then seemed to invoke
tracker-store automatically (I assume through a dbus service request) -
so dbus and the other deamons seem to be playing ball, just not
tracker-extract.
