dovecot - Feb 2012 - dovecot 2 doesn't start with managesieve

Hi

I build dovecot 2.0.16 and and dovecot-pigeonhole-0.2.5 on two machines with the
same options. The config files are equivalent. On the first machine everything
works fine - on the second dovecot with managesive won't start (without
sieve protocol it does).

	Error: socket() failed: Protocol not supported
	Error: service(managesieve-login): listen(::, 4190) failed: Protocol not
supported
	Fatal: Failed to start listeners

I controlled the config, build pigeonhole a second time - nothing helps. 

Any idea ? Is there a possibility to debug the start?

Nicola

...

plugin {
  
  ...
  
  sieve = ~/.dovecot.sieve
  sieve_dir = ~/sieve
}

protocols = imap pop3 sieve

...

service managesieve-login {
  inet_listener sieve {
    port = 4190
  }
  inet_listener sieve_deprecated {
    port = 2000
  }
}
service managesieve {
  process_limit = 1024
}

...

protocol sieve {
  managesieve_max_compile_errors = 10
}

You don't have IPv6 supported, so listening in "::" fails. Disable
it with:

listen = *
