I'm on ubuntu xenial, I installed python-pil which gives pillow 3.1.2

I'm trying to get exif metadata from an image shooted with a Canon PowerShot A80. which is at media_path:

from PIL import Image
from PIL.ExifTags import TAGS, GPSTAGS
image = Image.open(media_path)
info = image._getexif()

the code works perfectly with all images but this and other images shooted with the same camera.

With this image _getexif() returns the empty dictionary.

gthumb and identify correctly read exif metadata of this image:

$ identify -verbose myimage
