[Debian-med-packaging] Bug#1049489: seqprep: Fails to build binary packages again after successful build

[Lucas Nussbaum]

Source: seqprep
Version: 1.3.2-8
Severity: minor
Tags: trixie sid ftbfs

Hi,

This package fails to do build a binary-only build (not source) after a
successful build (dpkg-buildpackage ; dpkg-buildpackage -b).

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/DoubleBuild
