During the backup only one - last - dialogue entry is backed up.

Proposed (and tested) solution - in the mod/dialogue/backuplib.php change the lines as follows:

#95

now: $status = backup_dialogue_entries($bf,$preferences,$conversation->id);

proposed: $status = backup_dialogue_entries($bf,$preferences,$dialogue);

We need to back up entries for the whole dialogue, not only for the last processed conversation, so consequently:

#105

now: function backup_dialogue_entries ($bf,$preferences,$conversationid) {

proposed: function backup_dialogue_entries ($bf,$preferences,$dialogue) {

#111

now: $dialogue_entries = get_records(dialogue_entries,conversationid,$conversationid,id);

proposed: $dialogue_entries = get_records(dialogue_entries,dialogueid,$dialogue,id);
