[Samba] Samba3 -> Samba4 migration

[miranda]

Hi, everybody

Im getting many troubles trying to upgrade to samba4 using
"classicupgrade" :

samba-tool domain classicupgrade --debuglevel=7
--dbdir=/produtos/backup/var/lib/samba/
--use-xattrs=yes  /produtos/backup/etc/samba/smb.conf

After some messages im getting an Segmentaion fault

Any hint in what should i investigate ?

Here is  my stdin :
