[Bacula-users] Why is it isuing a list command when no barcode ?

[<ba...@pi...>]

Bacula was working OK before my upgrade 1.36.3 -> 1.38.5.

The problem is that when I "update slots scan", I have the following actions :
(It even do not load each tape before telling that there is no volname.)

*update slots scan

I don't understand why I have the :
3306 Issuing autochanger "list" command. 
line, because I have no barcode, and the list command will return nothing.
orval bacula # mtx -f /dev/sg1 status
  Storage Changer /dev/sg1:1 Drives, 8 Slots ( 0 Import/Export )
Data Transfer Element 0:Empty
      Storage Element 1:Full
      Storage Element 2:Full
      Storage Element 3:Full
      Storage Element 4:Full
      Storage Element 5:Full
      Storage Element 6:Full
      Storage Element 7:Full
      Storage Element 8:Full
orval bacula # ./mtx-changer /dev/sg1 list
1:
2:
3:
4:
5:
6:
7:
8:
orval bacula #     

I'm a bit lost, I don't know why is my bacula not changing tapes correctly.
Perhap's did you already met this problem ?
