There seems to be a problem with our rotation algorithm (not the auto
rotation).

Mik,

take your image in the above screenshot and rotate it
-41.68°
in showFoto and Gimp. The Gimp version looks right, the showFoto version does
not.
I you take both results and paste them into a Gimp document, setting the top
layer to "difference", you can see the problem more clearly.

Somehow rotating to the left is wrong.

Gilles,

any idea?
Can someone confirm this difference between showFoto and Gimp?

Andi
