Git commit 613d004121682d122e9ea7fd9041a7bbc49acb89 by Gilles Caulier.
Committed on 07/01/2013 at 11:34.
Pushed by cgilles into branch 'master'.

Apply patch #76256 from Roman I Khimov to use crop factor from camera, not from lens data.
Lens crop factor in DB only tells us which crop factor was used for lens
calibration data, but it has nothing to do with shots made on random user's
camera. So the default behaviour should be to use camera's crop factor and only
fallback to lens data if there in no data present for camera. As "this should
not happen" it's appropriate to spit out some debug message in this case.
