The problem is that code for parsing Packages files was too fragile. It assumed that every "paragraph" was separated by exactly one blank line, but the Ubuntu Packages file has at least one place where there are two blank lines. None of the official Debian files ever exhibited this, I guess. The fix should be simple.
