While trying to understand and solve this problem, I tried to find what was
special with the files for which I'm encountering the issue.  This is what I
get with exiv2 :

$ exiv2 pr geo-tagging_fails.jpg

Since digikam uses libkexiv2, could this be causing the problem?

I don't really understand the JPEG internal structure, but I will try to find
if I can remove or fix what makes exiv2 unhappy with exiftool.
