I did try this, but it doesn't seem to work. If there's an unescaped
percent sign in the URL, LaTeX dies with "Paragraph ended before
\htmladdnormallink was complete.". You're right about being able to
change the \_ to _, though; I just recently discovered the url
package, so I'm still learning these things ;)
Here's a minimal LaTeX document:
--------------------- main.tex -----------------------------------------
\NeedsTeXFormat{LaTeX2e}
\documentclass{article}
\begin{document}
\nocite{*}
\bibliographystyle{acm}
\bibliography{main}
\end{document}
------------------------------------------------------------------------
and here's a more minimal bibtex file:
--------------------- main.bib -----------------------------------------
howpublished = {fffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffff\%ggggggggggggg},
}
------------------------------------------------------------------------
the .bbl I see from this is:
--------------------- main.bbl -----------------------------------------
\begin{thebibliography}{1}
\bibitem{qrp}
fffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffff\%
%ggggggggggggg.
\end{thebibliography}
------------------------------------------------------------------------
In the final dvi output, none of the g's appear.
Obviously, this is very contrived, but my initial example was quite
real :>
I'm using regular latex to generate my output.
(In my original bug report, I was using a different bibliography style
(IEEE) not included in the standard distribution, but I was able to
reproduce the problem easily enough with the acm style, which I
figured would be easier.)

These are good things to know, but it looks like the problem occurs
without hyperref and with any bst file. :-( (Input that breaks in one
bst file may work fine in another, but for any given bst file there is
some input that will work incorrectly)
Let me know if I can be of any further assistance.
