Description of problem:
When you run "jpegtran -rot 90 -copy all x.jpg > y.jpg", the EXIF information isnt' re-written to contain the correct "Image Data/Orientation" field as it should be.
EXIF-aware applications will display the image incorrectly if this field is not correctly modified to reflect the true encoded orientation.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Find a JPEG image that contains EXIF orientation data.
2. In nautilus, right click it, and view the EXIF data. Note the "Image Data/Orientation" field.
3. run "jpegtran -rot 90 -copy all x.jpg > y.jpg"
4. In nautilus, right click the new y.jpg file, view the EXIF data again, and not that the "Image Data/Orientation" field has not been updated.
