[Dovecot] managesieve login fails

[Leander S.]

Hi,

when I try to make use of the managesieve capability maillog always shows:

server dovecot: managesieve-login: Panic: file client.c: line 449 
(client_set_auth_waiting): assertion failed: (client->to_auth_waiting == 
NULL)
server dovecot: dovecot: child 5926 (login) killed with signal 6 (core 
not dumped) (ip=192.168.1.233)

... and Thunderbirds remote sieve optimizing plugin won't connect ...



Otherwhise IMAP & POP authentication, etc. ...  is working proper.
