Photos in "portrait" not working

I have a problem displaying photos (jpg) in portrait format on my Samsung 40D7090: Not supported file format
Photos in the same folder but in landscape format are working. I have not rotated the photos manually.
Any ideas?

Setting autorotation to "false" solves the issue. No idea why though...

This error has been already described in the forum. It is probably due to the metadata and your samsung firmware.
