SVN commit 824710 by cgilles:

libkexiv2 from trunk : add special case to handle TIFF writting mode properly. we need to load taget TIFF image metadata before to update it, else the image will be broken. look my comments on source code for details.
Hurra : this is want mean than TIFF metadata can be updated on the fly, like JPEG, without to touch image data.

I am afraid still no bananas :(

Works for Captions (as Exif, IPTC, XMP) but tried to modify few other
fields of Exif (Name, Copyright, Artist) and image is broken.
