[Python-modules-team] Bug#838646: python-markdown: FTBFS in testing (OSError: Could not load libtidy)

[Santiago Vila]

Package: src:python-markdown
Version: 2.6.6-1
Severity: serious

Dear maintainer:

I tried to build this package in stretch with "dpkg-buildpackage -A"
(which is what the "Arch: all" autobuilder would do to build it)
but it failed:
