I have added an testimage and a version processed by f-spot 0.5.0.3 (just saved) which use libexif 0.6.17. My system is using Linux OpenSuSE 11.1 on an x86_64 mashine. Also the output from exiftool of the two images are added.
The problem still exist in libexif 0.6.17. I have also tested to process images from other cameras in the same way with good result (Olympus FE-20, SONY DSC-W5).
