[Dovecot] Segfault in managesieve with "sieve_extensions = -redirect"

[fakessh @]

I do not understand certain things in your dovecot-n

in my dovecot -n
there is a 
plugin {
  plugin =  autocreate managesieve  sieve
  sieve = ~/.dovecot.sieve
  sieve_before = /var/sieve-scripts/roundcube.sieve
  sieve_dir = ~/sieve
  sieve_global_path = whatever
  autocreate = Trash
  autocreate2 = Junk
  autocreate3 = Sent
  autocreate4 = Drafts
  autosubscribe = Trash
  autosubscribe2 = Junk
  autosubscribe3 = Sent
  autosubscribe4 = Drafts  
}

this missing in your config
