I have no clue why, but while polipo does start normally, privoxy in 12.1 64bit seems broken. As seems broken also tor.
In yast trying to start the service you get :
failed - error 1 - unspecified error.

Tor can be started by hand. But although it has been granted access rights either as file system as by apparmor to /etc/tor/torrc it claims:
pr 04 07:57:39.123 [notice] Tor v0.2.2.35 (git-b04388f9e7546a9f). This is experimental software. Do not rely on it for strong anonymity. (Running on Linux x86_64)

But why, it has full access to /etc/tor/torrc??????

And then when you try with privoxy it fails miserably without giving you great explanation on why:
# rcprivoxy start
redirecting to systemctl
Job failed. See system logs and 'systemctl status' for details.
So you go to system logs:
Apr  4 09:43:40  privoxyd[16468]: Starting Privoxy..failed
Apr  4 09:43:40 systemd[1]: privoxyd.service: control process exited, code=exited status=7
Apr  4 09:43:40  systemd[1]: Unit privoxyd.service entered failed state.
Apr  4 09:44:08  kernel: [ 6646.665328] intel ips 0000:00:1f.6: MCP limit exceeded: Avg power 35143, limit 35000
So, what is the issue, this seems all connected. Please if you can help me on this, I will be grateful.

P.S. The MCP is a kernel/acpi issue that arrives with strigi activating. So it has already reported and is not connected.
