Hm... I rely on HTML::parser to take care of this. You might try this: in
HTML::Parser, line 172, change:
                    } elsif ($$buf =~ s|(^=\s*([\"\'])(.*?)\2\s*)||s) {
to
                    } elsif ($$buf =~ s|(^=\s*([\"\'])(.*?)[^\\]\2\s*)||s) {
which *should* allow you to escape the ' with a \.

RFC1866 doesn't allow the quote to be in the string, and says you have to use
&#34; for double quotes and &#39; for single quotes.
(http://www.faqs.org/rfcs/rfc1866.html) Try that, I guess. BTW, are you sure
you need to put single quotes in the popup? You could use EscapeHTMLChars
(from HTMLTools) on %{description} in the handler.

Good luck,
David
