[squid-users] Problem with ssl bump: Error negotiating SSL connection

Hello,

I am tryng to setup a ssl bump with squid3. However I get always this error:

2012/09/25 09:58:33| clientNegotiateSSL: Error negotiating SSL
connection on FD 10: error:1407609B:SSL
routines:SSL23_GET_CLIENT_HELLO:https proxy request (1/-1)

The relevants snippets of my configuration:

http_port 3128
https_port 3133 ssl-bump cert=/etc/squid3/self_signed_cert.pem
key=/etc/squid3/self_signed_key.pem
(..)
always_direct allow all
ssl_bump allow all
sslproxy_cert_error allow all

----
I tested several different https websites but I get always the same error
I have also tried to add the dangerous option 'sslproxy_flags 
DONT_VERIFY_PEER ' but it don't made any difference.
There is a compiled squid3, the '-v' output is:
root_at_z3:/etc/ssl# squid3 -v
