The new PHP5 strict standards require to initialize objects using new stdClass(); call. The config file doesn't do so on lines 27 and 126:
Line 27 should be:
$conf = new stdClass();
Line 126 should be:
$conf->domains[$i] = new stdClass();
this needs to be propagated for each new domain entry.
Thank you very much for the hint!
It is now fixed in SVN (In Revision 2382) and will included in the next NOCC version.
