I have discovered a work-round for today: If I delete one line from
the final description in the Packages file, apt-get and apt-cache
work without a problem. The description section is 14 lines long
before deleting the final line, so this is a very odd one. I can't
say whether the same is true of the Packages file I sent in the
original bug report.
