tracker extract seems to generate invalid RDF for PDF images
I have a number of single page PDF files that are just a single image. When tracker extract runs on at least some of these, it generates a property 'nfo:orientation nfo:orientation-top ;'
When the miner attempts to write this into the database, it fails with an error of the form:
Subject 'urn:uuid:e53fb03f-aafe-8371-6265-f90f7b3780f5' is not in domain 'nfo:Image' of property 'nfo:orientation'
Thanks to the new behaviour of the miners, this gets spammed constantly into the logs until I remove the offending files or add an ignore directive for the directory.
Here's an example: Forest_Pools.pdf
