Public bug reported:
Starting with a photo from a Canon camera that has orientation "rotate 90"
according to jhead, or "right - top" according to exif.
Scale it smaller with imagemagick's "convert". Check that jhead and exif still
think the orientation is the same. Now try to view or remove the orientation
with jpegexiforient, and it fails.
$ convert -scale 600 vertsav.jpg vert.jpg
$ jhead vert* | grep Orien
Orientation : rotate 90
Orientation : rotate 90
$ exif vert* | grep Orien
Orientation |right - top
Orientation |right - top
$ jpegexiforient vertsav.jpg

$ jpegexiforient vert.jpg
$ jpegexiforient -1 vert.jpg
$ jhead vert.jpg| grep Orien
Orientation : rotate 90
$ exif vert.jpg| grep Orien
Orientation |right - top
