Comment 1 for bug 1433747

Thanks for the detailed report. pyexiv2 is not actively maintained any longer, it has been deprecated in favour of https://wiki.gnome.org/Projects/gexiv2.

As you point out, it looks like the issue could be in exiv2 itself. You might want to file a bug with all those details at http://dev.exiv2.org/projects/exiv2/issues.
