Looks like Exif data from a JPEG image in a TIFF file. E.g., it has thumbnail
tags, which are common in JPEG, but here they turn this image into a multi-page
TIFF image (and apparently an invalid one due to the JPEG thumbnail) - probably
not what was intended.

This is a combination of bug #183171 and the issue discussed here
http://dev.exiv2.org/boards/3/topics/show/20, I guess.

Exiv2 is not user-friendly when writing to TIFF. Currently, an application must
make sure it writes only valid tags to TIFF images and preserves tags which are
needed for the image itself. But if it does that, it will work. See the exiv2
command-line tool for an example, a pointer is in the thread mentioned above.
