I use the face recognition feature, and as I understand it when it's scanning pictures it assigns a tag "scanned for faces" to mark which ones have been scanned already. It's apparently a kind of "internal" tag as it doesn't show up in Digikam GUI.

So far so good.

However if I allow Digikam meta-data to be stored in Nepomuk, the tag "Scanned for Faces" appaears in Dolphin in the list of tags available in the faceted search panel. I think this tag was intended for an internal use and should not appears in any UI.

As a side effect (I think); If i allow digikam to read meta-data from Nepomuk after this, the "Scanned for Faces" tag also appears in the GUI, on every picture already scanned. Apparently when it goes to Nepomuk it lost his "internal" aspect and becomes visible in Digikam.

Reproducible: Always

Steps to Reproduce:
Use face recognition
Activate "store digikam metadata in nepomuk" in the configuration option

Actual Results:  
"Scanned for Faces" appears in the tag list available to search with in Dolphin.

Expected Results:  
The tag list in Dolphin should only show the normal tags used in Digikam and in Nepomuk, and not this one which I think only exists for some internal process in Digikam.
