Metadata extracted from NEF with exiv2

Andreas, find attached metadata from a NEF file extracted with exiv2.
Then I have taken a TIFF image
(http://digikam3rdparty.free.fr/TEST_IMAGES/TIFF/Solar_Spectrum.tiff) and
inserted the metadata with "exiv2 in".
Afterwards, GIMP gives the typical error messages:

/home/marcel/Solar_Spectrum.tiff: invalid TIFF directory; tags are not sorted
in ascending order
/home/marcel/Solar_Spectrum.tiff: wrong data type 7 for "Photoshop"; tag
ignored
/home/marcel/Solar_Spectrum.tiff: wrong data type 7 for "Photoshop"; tag
ignored

/home/marcel/Solar_Spectrum.tiff: unknown field with tag 11 (0xb) encountered
/home/marcel/Solar_Spectrum.tiff: unknown field with tag 18246 (0x4746)
encountered
/home/marcel/Solar_Spectrum.tiff: unknown field with tag 18249 (0x4749)
encountered
/home/marcel/Solar_Spectrum.tiff: unknown field with tag 11 (0xb) encountered
/home/marcel/Solar_Spectrum.tiff: unknown field with tag 18246 (0x4746)

/home/marcel/Solar_Spectrum.tiff: unknown field with tag 18249 (0x4749)
encountered
TIFF-Bild: /home/marcel/Solar_Spectrum.tiff: wrong data type 7 for "Photoshop";
tag ignored

The former three in a dialog, the latter on the console.
The picture itself can be opened by gimp, but there are other example images in
some of the four bug reports merged here that are more severely broken.
So keep in mind there could be two distinct problems, but we should assume it's
one problem and fix these warnings.
