--- Comment #13 from Gilles Caulier <caulier.gilles at gmail.com> ---
First problem confirmed Libraw 0.16 cannot extract embedded preview and half
preview with this DNG file :

digikam(75049)/digikam (core) Digikam::ThumbnailCreator::load: Thumbnail is
null for  "/Users/gilles/Pictures/photos.test/hdrmerge_045.dng" 
digikam(75049)/digikam (core) Digikam::ThumbnailCreator::createThumbnail:
Trying to load Embedded preview with libraw
digikam(75049)/digikam (core) Digikam::ThumbnailCreator::createThumbnail:
Trying to load half preview with libraw

This debug statements just proof that libraw is not able to work with this file
without to use a full demosaicing method.

Typically this DNG is badly encoded by HDRMerge.
