Hold your horses! :P Those errors are parsing desktop files:

14 Sep 2011, 11:11:44: Tracker-Warning **: Invalid desktop file:
'file:///usr/share/desktop-directories/X-Unity-All-Applications.directory'
14 Sep 2011, 11:11:44: Tracker-Warning **:   Couldn't get name,
missing key (Name)
14 Sep 2011, 11:11:45: Tracker-Warning **: Couldn't properly parse
desktop file 'file:///usr/share/desktop-directories/vmware-ace-vms.directory':
'Desktop file doesn't contain type'

My guess here is that after parsing a desktop file we don't check that
we have values in the mandatory properites while generating the
sparql, then we produce a broken sparql. Can we get one of those
.desktop files?

Then comes a bunch of dbus errors with the extractor, so probably
tracker-extract is crashing with some files. Would be great if we
could either get those files or a backtrace to fix the problem. I
wonder if it is related with the EMF format that we don't support. We
shouldn't crash or stop processing other things because of that...

That tracker is also configured to scan everything under /, which is
not recommendable. (Is this related with the gvfs bug?)

Also, something is wrong with the gstreamer plugins and/or the
mimetypes, because the log says:
09 Sep 2011, 12:43:07: Tracker-Warning **: Call to
gst_discoverer_discover_uri() failed: Your GStreamer installation is
missing a plug-in.
09 Sep 2011, 12:44:50: Tracker-Warning **: Call to
gst_discoverer_discover_uri() failed: This appears to be a text file

And your PDFs doesn't work fine with poppler:
9 Sep 2011, 14:53:32: Tracker-Warning **: Couldn't create
PopplerDocument from uri:'file:///home/rkrug/Documents/xxxxxxxx.pdf',
PDF document is damaged

Next step is to get those problematic .desktop files, ping the
maintainers to fix them ;) and make our parser more robust. Then fix
the extraction for those problematic files. We can use
http://filetea.me to share them.
