I forgot to write:

- this is with dovecot 1.1.2

- this is not specific to INBOX: when saving a message from a folder to 
  the same folder, Alpine complaints with the message
  [Can't copy mails inside same folder ]

- the debug journal of Alpine shows, with a 'news' folder:

IMAP DEBUG 09:46:05 8/20: 0900000b COPY 100 news
IMAP DEBUG 09:46:05 8/20: 0900000b NO Can't copy mails inside same mailbox


- a quick grep shows this is 'normal' behaviour, as written in 
  src/lib-storage/index/mbox/mbox-save.c

                        if (mbox->mbox_lock_type == F_RDLCK) {
                                /* FIXME: we shouldn't fail here. it's just
                                   a locking issue that should be possible to
                                   fix.. */
                                mail_storage_set_error(storage,
                                        MAIL_ERROR_NOTPOSSIBLE,
                                        "Can't copy mails inside same mailbox");
                                return -1;
                        }
