Sorry for asking the trivial: are you sure you byte-compiled the
modified browse-url.el and loaded it into Emacs before trying?

If indeed the modified code still doesn't solve the problem, please
step with Edebug into browse-url-default-windows-browser when it is
called after you tell report-emacs-bug you want to send via
mailclient, and see what URL is being passed to w32-shell-execute.  It
should be a mailto URL with all the special characters, including the
quotes, encoded as hex %nn codes.  Copy that URL, then paste it into
the Windows Start->Run dialog, and see if that causes the same error
message as you get in your testing.
