After deleting an image and browsing back and forth over the pace where the image was, the navigation still "thinks" that the image is there.

To reproduce:
* Start MP
* Goto MyPictures
* Open 1st picture by selecting an press Enter
* Press right arrow for second picture
* Delete this picture with pressing 0
* Now press left arrow to go back to picture 1
* Nothing happens!
* Press left arrow again
* 1st pictures appears
* press right arrow
* nothing happens!
* press right arrow again
* 3rd image appears

So navigation still "thinks" image 2 is there.
