    That would be e.g.,
    
http://debian.linux.org.tw/debian/pool/main/m/mediawiki1.7/mediawiki1.7_1.7.1-1_all.deb

I got that file but I can't reproduce the problem.
What major mode was used when you visited it?

Please tell me precisely what to type, starting with `emacs -Q',
to make this problem happen.
