Well I just tried this with photos from my D70. The result were images that 
were completely wrong rotated. 

What I did was to copy D70 unprocessed images to a digikam album. In the 
config of digikam I have the option "rotate according Exif" turned on. The 
images are displayed in correct rotation in digikam.

Next I selected "Image->Autorotate/Flip using Exif". The result should be 
images that are really rotated according to their exif information so other 
applications not aware of EXIF data display the images correctly anyway.

Afterwards images that were previously correctly displayed in digikam in 
landscape are suddenly displayed in Protrait Mode and are now wrong. The 
Images that really need protrait mode are still in displayed in landscape.  
So the result is complete nonsense now. Next I tried to select the menu 
"Correct EXIF orientation tag". But this did not change anything. If I now 
look at there images in konqueror I see the same problems. So it seems that 
the images have been rotated but in a wrong manner.

If I turn off the checkbox in digikam settings  "rotate according to Exif" the 
very same trouble is there after selecting "Image->Autorotate/Flip" on the 
photos.

I guess there is still a bug.

Usually I do this using jhead -autorot -exonly *.jpg which always works fine 
for me.

Have a nice day
Rainer
