Package: ftp.debian.org `dak rm -b ${package}` or other variants do not when when `${package}`'s source is already removed. This happened with lostirc (bug #1024341).
The cause is likely the SQL queries in dak/rm.py that include +--- | JOIN newest_source on s.source = newest_source.source AND su.id = newest_source.suite +---[ dak/rm.py ] which then results in an empty set if `${package}`'s source is no longer in the suite. Ansgar
