I'm using digikam 0.8-beta1 already. Hope to see the new kiki-plugins soon...

Thanks for the tip! exiv2 is exactly what I was looking for!
Now I need a list with important tags ... 
I guessed already correctly that orientation is Exif.Image.Orientation so my 
biggest problem is solved!
I'm still having troubles with images that had no exif header at all before, 
When just adding an orientation tag. It shows up in the preferences, but I 
can't change it and the picture doesn't get rotated in the thumbnail-view. 
But the viewer (the one that opens, when I double-click on the thumbnail) 
does rotate it! Strange thing ... (And yes, I do have that feature activated, 
other thumnails get rotated)
