Hi,

I've reported this bug already sometime ago and we thought that it is resolved
now.
Because we have now a re-written code I think it is better to track this in a
new bug report.

While testing the program I discovered that sometimes assigning or changing a
color profile to a TIFF-16 worked and sometimes not. After a while I found out
the cause:
If exiv2 0.17 (which is the lib version installed by default in kde) is used
assigning the color profile works perfectly. Using version 0.18 or 0.18.2 (and
recompiling libkexiv2 and digikam of course) is does not work. There is no
difference whether exiv2 is installed via rpm or by compiling from source.

This is bad, because exiv2 0.17 does not support writing meta to TIFF.
