This is highly embarrassing. Povray 3.8 sets the aspect ratio depending on the
image format. So I didn't set the right vector in the camera.
The #version in my pov-file was set to 3.7 however, and then the aspect ratio is
1.33.
There are some hawk-eyed people out there. Thanks everybody.

BTW as excuse for myself: As long as there are no circles in your object, you
hardly notice! Poor excuse, I know, but better than nothing.

Cheers
