My father has reported (in a not very coherent way) that after a recent update (presumably security fix for libTIFF?) he is also getting errors with some, but not all, TIFF images downloaded in the past from a genealogy site.

Hopefully this will be fixed soon, but if not I can get and post an example image in the near future.

I just tried to build the libtiff package from source with the following to get the packages needed:

sudo apt-get build-dep tiff
apt-get source tiff

This has some errors on verifying:

Which organisations public key is missing?

But more importantly I don't see the line mentioned above in the source tif_fax3.h, where as I do see it mentioned in the patch tiff_3.9.2-2ubuntu0.4.diff

Why is it not being applied here, as it said it did in the last line?
