[Python-modules-team] Bug#870469: Should use a fork of pdfminer

[VA]

Package: python-pdfminer
Version: 20140328+dfsg-1

python-pdfminer upstream is unmaintained and is not compatible with 
Python 3: https://pypi.python.org/pypi/pdfminer

However, there's a drop-in fork which is Python 3-compatible and 
maintainted:
https://pypi.python.org/pypi/pdfminer.six
https://github.com/pdfminer/pdfminer.six
It could be used instead.
