Web Access and IPv4

After adding VMWare Server 2.0.2 to a current testing (Squeeze) amd64 install, which was easy enough following this Wiki, thanks, the web interface at both ports 8222 and 8333 just gave me an empty page after the certificate had been confirmed, both in Iceweasel and Konqueror. Following the recommendation at http://derickrethans.nl/vmware-debian.html made the web interface accessible in my IPv4 only LAN. It goes

"Simply add -Djava.net.preferIPv4Stack=true in /etc/init.d/vmware-mgmt to the line (line 678 for me) starting with webAccessOpts="-client. I've added it just before -Djava.util.logging.manager=org.apache.juli.?ClassLoaderLogManager"
