What is "all ok"? Should it be rotated or not? What options have you set?

>    - go back to the album view (ESC or mouse-click)
>    - open this image in the image editor (F4)

Why should it not be rotated? Or is is rotated twice?

When loading a preview, the cache is searched in this order:
1. Full image
2. Preview image

This means if the Image Editor has loaded a full version, it will later on be 
preferred over the preview version, when loading a preview. Can this explain 
the behavior?

It must never happen that when loading a full version, the reduced version is 
returned.
