error starting up Zimbra desktop (one solved, one not)

[mosu]

Hi,
I had troubles installing Zimbra Desktop 2.0. Process hangs in a .. browser window.
I noticed Jetty, then I realize Jetty is messed by the presence of IPV6. Or java is.

So I had to add -Djava.net.preferIPv4Stack=true to java opts
and it worked.

Yet, after creating mail account (successful) a notice appears saying my "network connection lost. you are now offline".
Imagine my connection is just fine.
Looking in logs (~/zdesktop/log/zdesktop.out and zdesktop.log) reveals nothing:
