Here is a patch to port libexif-gtk to the new libexif API.
Patch that ports to the new syntax of gtk_list_store_set() and exif_entry_get_value()
Author: Marcus Meissner
Patch that gets rid use of broken-by-design exif_tag_get_name()
Second patch discovers hole in the libexif API: missing function for getting all known tags. Additionally, definition of ExifTag as enum is not wise, as some tags are not unique. They are unique only per IFD.
