Bug#1024404: gitlint: reproducible-builds: python tracebacks in gitlint.1 man page

[Vagrant Cascadian]

Source: gitlint
Severity: important
Tags: patch
User: reproducible-builds at lists.alioth.debian.org
Usertags: buildpath
X-Debbugs-Cc: reproducible-bugs at lists.alioth.debian.org

The output of a python traceback including the build path is embedded in
the gitlint.1 man page:

  https://tests.reproducible-builds.org/debian/rb-pkg/unstable/amd64/diffoscope-results/gitlint.html

  /usr/share/man/man1/gitlint.1.gz

  .TH·TRACEBACK·"1"·"December·2021"·"Traceback·(most·recent·call·last):"·"User·Commands"

Though embedding the build path revealed the problem, the real problem
is caused by missing dependencies...

The attached patch to debian/control fixes this by passing adding
several python3 packages to Build-Depends, as using help2man requires
the run-time dependencies at build-time.

According to my local tests, with this patch applied gitlint should
build reproducibly on tests.reproducible-builds.org as a side-effect of
fixing the real problem!

Thanks for maintaining gitlint!

live well,
