Face tag plugin & auto exif rotation [solved]

Check this option : Settings > General > "Rotate images according to EXIF orientation tag"
For photos that are not in natural orientation :
- When the option is enabled, the Face tag plugin can detect faces, but displays wrong regions.
- If the option is disabled, rotated faces are not detected
(in this case, we can manually define regions and add names)

Download the photo and browse with Xnviewmp ...
1) Disable rotation according to exif
- No face detection. It is not surprizing.
- user defined regions : all OK
2) Enable exif auto rotation
Face detection ok, but
wrong place for regions 
-user defined regions :
