[Reproducible-builds] Bug#796490: [texlive-latex-base] pdflatex does not create reproducible pdfs with multiple images

[Sandro Knauß]

Package: texlive-latex-base
Version: 2014.20141024-2
Severity: normal
X-Debbugs-CC: pkg-owncloud-maintainers at lists.alioth.debian.org

Hey,

While testing why the owncloudClient pdf is not reproducible, we found a bug 
in pdflatex. The minimal document to triggerthis bug is a document with 4 
pictures and a tableofcontent. The outcome is, that pdflatex creates every 
time a different pdf (it differs in the emeded images). We tried with less 
pictures and no tableofcontent and afterwards the pdf was reprocubile. As far 
as we tested it is only triggered with png and not with jpg.

One workaround is to use optipng for all input pngs, that made the pdf also 
reproducible.

Regards,

sandro
