Bug#1049512: gnutls28: Fails to build binary packages again after successful build

Source: gnutls28
Version: 3.8.1-3
Severity: minor

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
