So you want to get your bug fixed but don't want to even give your email address to the people that will fix your bug? (aka everybody, since this is OSS). What a weird point of view. Email addresses --you need to share them to allow people to message you. That's how they work. And this is really a nonissue since getting more addresses is so damn easy (well, spam and spambots is another story and the reason one might hide them from the open internet)... Facebook didn't get in trouble because of this.
