Bug#960882: exiftran: Exiftran corrupts image

[Alexis Huxley <alexishuxley@gmail.com>]

Package: exiftran
Version: 2.10-4
Followup-For: Bug #960882

Dear Maintainer,

I have the stock version of package fgallery installed:

farfalle$ dpkg -l fgallery
Desired=Unknown/Install/Remove/Purge/Hold
| Status=Not/Inst/Conf-files/Unpacked/halF-conf/Half-inst/trig-aWait/Trig-pend
|/ Err?=(none)/Reinst-required (Status,Err: uppercase=bad)
||/ Name           Version      Architecture Description
+++-==============-============-============-============================================
ii  fgallery       1.8.2-2.1    all          static HTML+JavaScript photo album generator
farfalle$ 

fgallery's image processing results in images with exactly the same 
corruption reported in this ticket.

fgallery has dependencies:

farfalle$ apt-cache show fgallery | grep ^Dep
Depends: libimage-exiftool-perl, libjson-perl, imagemagick, exiftran | libjpeg-turbo-progs, libjs-mootools (>= 1.4), zip | p7zip-full
farfalle$ 

Note there is exiftran *or* libjpeg-turbo-progs and I do not have 
exiftran installed, but do have libjpeg-turbo-progs installed:

farfalle$ dpkg -l exiftran libjpeg-turbo-progs
Desired=Unknown/Install/Remove/Purge/Hold
| Status=Not/Inst/Conf-files/Unpacked/halF-conf/Half-inst/trig-aWait/Trig-pend
|/ Err?=(none)/Reinst-required (Status,Err: uppercase=bad)
||/ Name                Version      Architecture Description
+++-===================-============-============-====================================
un  exiftran            <none>       <none>       (no description available)
ii  libjpeg-turbo-progs 1:2.0.6-4    amd64        Programs for manipulating JPEG files
farfalle$ 

This makes be believe that *neither* exiftran nor libjpeg-turbo-progs 
are *directly* responsible for the corruption, but rather a common 
dependency of exiftran and libjpeg-turbo-progs is responsible.
