Hi,

during my attempts to find out what is cause for the undo/revert-bug I
discovered a new one:

When using digikam with exiv 0.17 it saves TIFF-16 compressed and uncompressed
without problems. Using exiv2 0.18 or 0.18.2 (and recompiling libkexiv2 and
digikam of course) saving TIFF-16 compressed results in an image looking like
someone has used an emboss filter. 

Here is an example:

And so it should be:
http://www.dolphin-world.de/images/Bild_M2c_061i.tif

I have tried to use exiv2 0.18 from rpm and by compiling by myself: no
difference.

TIA
Guenther
