doveadm backup Error: Mailbox INBOX sync

Hi,

the command  "doveadm  backup -u {user@mail} maildir:/home/backup/{user@mail}/mails/" returns the following error :

dsync(user@mail): Error: Mailbox INBOX sync: mailbox_delete failed: INBOX can't be deleted.

...and nothing in dovecot logs

 dovecot actual version 2.3.15

I did not have this pb in dovecot 2.3.2

/Should this be considered a bug report?/
