Bug 512040

SUMMARY
If a face tag under People is named the same as a normal tag elsewhere in the tag tree, detection of this face becomes impossible.

STEPS TO REPRODUCE
1. Make a regular tag named e.g. "Person1" somewhere in the tag structure (in my case it was one level deep)
2. Create a tag with the same name under People in order to detect and find an associated face
3. Assign some detected faces to the People/Person1 tag
4. Run face detection on pictures which contain the same face
5. The face is not tagged (or maybe it's just a display thing - it does not appear under People/Person1, but the label does appear when I view faces in Preview for a specific image).
6. Re-running faces detection doesn't help
7. After removing the regular tag and re-running face detection, faces for Person1 are detected automatically in images based on the manually tagged examples, just as they should.

It seems that despite being under a different path, the tag in People and the regular tag somehow conflict and prevent the face from being detected.

OBSERVED RESULT
The face is not detected in images in which it is detected if the non-People tag is removed.

EXPECTED RESULT
The existence of a regular tag with the same name as a tag under People should not affect face detection.
