I looked through the code and found that kipi dngconverter implemented a
different compression scheme than that described in adobe documentation.
Nevertheless there is also a bug in this implementation, so are all embeded
originals are lost. Meanwhile I have a test implemetation based on zlib working
with the adobe compression scheme. There is also Qts smarter qCompress, but
this gets a different result at the moment.
