That message was sent a few days ago, but got lost in a moderation process... I'm sending it again via another channel.

It seems that I have found a reason. As I have been told Privoxy is only a "web proxy" not "SOCKS5 proxy" and doesn't "understand" SOCKS5 protocol. I don't know why I stubbornly wanted to use it despite of pure Tor works as a SOCKS5 proxy very well... Sorry for inconvenience and thanks for your support.
