[Debian-med-packaging] Bug#1048644: pychopper: Fails to build source after successful build

[Lucas Nussbaum]

Source: pychopper
Version: 2.7.3-1
Severity: minor
Tags: trixie sid ftbfs

Hi,

This package fails to build a source package after a successful build
(dpkg-buildpackage ; dpkg-buildpackage -S).

This is probably a clear violation of Debian Policy section 4.9 (clean target),
but this is filed as severity:minor for now, because a discussion on
debian-devel showed that we might want to revisit the requirement of a working
'clean' target.

More information about this class of issues, included common problems and
solutions, is available at
https://wiki.debian.org/qa.debian.org/FTBFS/SourceAfterBuild
