Bug 320293

During the import, the exif orientation is not taking into account.
This is disturbing for the following tasks.

Reproducible: Always

Steps to Reproduce:
1. Copy the attached picture on a usb key
2. Import the picture from the usb key to your computer by using gwenview
3. Visualize the picture in gwenview
Actual Results:  
Due to the exif orientation, the visualization is good in gwenview and all other tool managing this exif orientation (example: dolphin, digikam, krita).
But, on the hard disk, the orientation still wrong.
So, the file is not well oriented if:
1-I push it on my web site
2-I send it by email
3-I replicate it to my drop box

Expected Results:  
Because I don't really understand why it could be interesting to have the wrong orientation on the hard disk, the import should:
1-Use the exif orientation to apply the rotation of the picture
2-Remove the exif orientation to avoid to use it twice (one during the import, the second one for visualization)

As work around, I use the rotate function but it's disturbing because:
1-In gwenview the orientation is good on the screen but bad on the file
2-I click on the rotate icon ==> the orientation is bad on the screen and bad on the file
3-I click on save icon ==> the orientation is good on the screen and good the file 
4-But now, how to know the pictures treated and the picture not treated?
