graphics/exiv2: request for inclusion of an upstream patch

[Andriy Gapon]

I am getting the following crash when I try to import a certain image with digikam:

#6  0x000000080687a55c in thr_kill () from /lib/libc.so.7

The image was taken with a Nokia phone camera and contains some non-empty
Exif.Photo.MakerNote (type Ascii, size 1088).

I believe that this issue was fixed upstream:
http://dev.exiv2.org/repositories/revision/exiv2/1743
http://dev.exiv2.org/issues/show/615
I applied this change in my local ports tree and it seems to fix the problem.

I also see that Debian folks have included this change into their package of
exiv2. Could we please do the same?

Thank you in advance.
