Torsten, plexus-build-api is used only on modello 1.0+, so it looks like you where using the wrong version of the sources. There was a uscan --upstream-version 0 in debian/rules which always download the latest version of the sources, regardless of the version given in the changelog, so that may be what happened to you.
I always use uscan --download-version $(DEB_UPSTREAM_VERSION) --force-download --rename as it's more reliable. Ludovic -- To UNSUBSCRIBE, email to debian-bugs-rc-requ...@lists.debian.org with a subject of "unsubscribe". Trouble? Contact listmas...@lists.debian.org
