Well, this doesn't help. There is no such files.
Here is the output of tracker-info which have only basic metadata because
the extractor failed:
Querying information for
entity:'file:///home/tracker/gnatbugs/62/6225-004/comment'

It is indeed a nfo:FileDataObject
My current command only check for some files that I know to have the
property nie:hasPart. it's what I am checking, but that wouldn't do for any
kind of files.
I would really like a tracker:error field so I could get the list of those
files easily
