I accidentally left out the Types: line. Should be:
--- start of code ----------------------------------------------- #NOTE: Most preferred source listed first! #=== NEW MULTI-LINE FORMAT =============== Types: deb deb-src URIs:http://ftp.uk.debian.org/debian/ Suites: stretch Components: main contrib non-free --- end of code -------------------------------------------------- But note that the bug occurs both with that missing line, and without it. So this follow-up is just so, you the maintainer, don't look at this and jump to the conclusion that the missing Types line has anything to do with this bug. It does not. In fact, this even more simple example with a single comment line followed by two blank lines, also demonstrates this bug: --- start of code ----------------------------------------------- #NOTE: Most preferred source listed first! --- end of code --------------------------------------------------
