Version:           1.2.0 (rev.: 1084045) (using 4.3.98 (KDE 4.3.98 (KDE 4.4 RC3)) "release 216", KDE:KDE4:Factory:Desktop / openSUSE_11.2)
Compiler:          gcc

If digikam writes exif data to a image some tags a destroyed after.

I look with exiftool to some imagemetadata an see that some data are wrong/unknown.
This is happened with a lot of pictures, so i take a new picture. This data are ok.
If i set a tag with digikam to this picture the data are broken.

Fixed with the new support of ExifTool to write metadata in place of Exiv2.
