Cannot update IP adress

Hi.

Ive tried updating my plesk installation with a new IP, following this guide: https://kb.plesk.com/en/943
But after i have edited the ipaddresses.map with the new IP adress and run: /usr/local/psa/bin/reconfigurator.pl ipaddresses.map

I get the following message:

Generating DB update script...
IPAddr instance has no attribute 'addr'

My Plesk is running on Ubuntu 14.04.4 LTS and my plesk version is 12.5.30 Ubuntu 14.04 1205160407.13

Do you guys have any idea to what might...
