btw: That example image is not the only one where I've seen this. 

Yes, something is really broken in those files' EXIF.  I cannot remove the
Orientation tag with ExifTool by "-Orientation=" command. It just does nothing.

I did the following now:
-Orientation=180      →  "1 image files updated"
-Orientation=90       →  "Can't convert IFD0:Orientation (matches more than one
PrintConv)"

The wrong orientation tag is only removable by ($1 = filename): 
exiftool $1 -exif:all=
exiftool -tagsfromfile $1_original --Orientation $1
And the second command reports "Warning: Missing stream for FPXR object 2 -
Solre-sur-Sambre_Station_plant-test.jpg_original"  -  but at least all EXIF
data is back but without the Orientation tag.

However, apparently - however - there are many/few files with broken EXIF. As
said, this is not the only file I have seen with this behaviour. 
Maybe the file isn't broken but some other tools like ExifTool are. -- What do
you expect from a tiff in a jpeg file mechanism? ;)
