Andreas,

The first stage done by digiKam core is to write a tiff file using libtiff...
until this step, i think tiff file is not corrupted. It's easy to reproduce a
file like this using ImageMagick, when you convert a JPEG to TIFF with convert
command line tool

The second stage call Exiv2 with libkexiv2 to update all digiKam metadata in
file. It's the more complicated stuff, because IPTC, and XMP are created, and
some exif tags updated (as image dim, orientation, comment, etc...)

Comparing satge 1 and stage 2 images with exiftool can be very instructive. We
can generate stage 1 file easily. There is only just one line to comment in
source code.

Gilles
