Package: pdftk
Version: 2.02-2
Severity: normal
Dear Maintainer,
In wheezy it was possible to use pdftk to alter the meta-data of a PDF
file. This functionality broke in jessie. Now there are warnings
which actually have the effect of errors (because no action is taken).
The warnings look like this:
pdftk Warning: InfoKey: (Title) already loaded when reading new InfoKey:
(Author) -- skipping newer item
pdftk Warning: InfoValue: (Bug Demonstration) already loaded when reading new
InfoValue: (Bug Submitter) -- skipping newer item
pdftk Warning: InfoKey: (Title) already loaded when reading new InfoKey:
(Subject) -- skipping newer item
pdftk Warning: InfoValue: (Bug Demonstration) already loaded when reading new
InfoValue: (Demo of how to alter PDF metadata in wheezy (broken in jessie)) --
skipping newer item
This script demonstrates the problem:

# This script demonstrates how to alter the metadata of a PDF. It's a
# self-contained example requiring no input files - only tools. These
# are the steps:
#
# 1) auto-generate a PDF file with some dummy text
# 2) update the metadata using pdftk
#
# Tools required:
#
# * LaTeX
# * pdftk
# * pdfinfo (optional)
# * evince (optional)
