Digikam stores some infos in an internal database. If you select an image and
use this command, digikam writes all information present in the database back
to the image, if they are somehow supported by exif, iptc and so on. So it
would be worth to select one of the geo-files and use this menu option. It
cannot destroy more than that single image. ;) So it would be worth a try if
the exif information is correct after that.

After this ans playing a bit with gqview I suspect that there is something
damaged in the exif information stored in the geo files. Opening this file in
gqview creates this warning:

exif tag unknown data size mismatch

Gilles:
Using the flickr api to set the location is of course something to be
implemented, but as far as I can see this bug is more about somehow damaging
the exif structure in the files. I'm really not into how this works. Who knows
how to debug this?
