Upgrade to v10 stops - AttributeError: no attribute 'split'

[mawe]

Hello!
Cannot upgrade to Scalix v10. The Uprade stops with the message:
AttributeError: error instance has no attribute 'split'

I have seen the other posts in this Forum and checked my DNS. But everything seems to be OK.

--------------------------------------------------------------------------
nslookup mail.zzzz.net
Name: mail.zzzz.net
Address: 192.168.xxx.6

nslookup 192.168.xxx.6
6.xxx.168.192.in-addr.arpa name = mail.zzzz.net.
--------------------------------------------------------------------------
/etc/hosts:
127.0.0.1 localhost.localdomain localhost
192.168.xxx.6 mail.zzzz.net mail
