[Samba] Samba4 domain classicupgrade "conversion not supported"

[Juan Asensio Sánchez]

Hi

I am running the "samba-tool domain classicupgrade", and after solving some
problems (thread
http://lists.samba.org/archive/samba/2013-January/170777.html), now I am
getting this error:

I think the problem is:

About to write CurrentVersion with type (null), length 3: 6.1
convert_string_talloc: Conversion not supported.

Type null? Is normal the suffix hive=NONE? What is the conversion that
generates the error?

Regards.
