TorButton and information disclosure on last OR

[Mansur Marvanov <nanorobocop@xxxxxxxxx>]

Hello!

I have a Client machine with TorButton (Tor client + Firefox + Privoxy
+ TorButton) and a Server machine with Apache.
But when I'm trying to connect from Client to Server through TOR
network I see that there's my information on HTTP-headers on Server
side that last OR gives to my Apache.
So, AFAIU last OR has all information about me? Isn't it disclosure of
information?
I think that it would be better if TorButton changes or deletes
HTTP-headers that could disclose me.
For example, at least TorButton could hide my Host header, by it
doesn't.. Is it a bug or what?
