I get these, too. I did not investigate that further yet as it seemed to
me that they did not have any real impact on anything. But it is on my
ToDO list (what isnt?)

Which version of shared-desktop-ontologies are you using?

This is the strigi indexer producing invalid data. This has been "fixed"

This might be fixed in libstreamanalyzer master. Could you test that?
