I'm running the VMWare Open edition.
In the bugzilla, I saw something with similar problem ... it has been corrected in the M4 (and I'm on 3.0.0_GA_156.FC4 FOSS Edition so I don't know if this has been on my version too ...
).
Concerning your link, it doesn't work too ...
Is this error related to a connection problem or a filtering problem (I don't think the RSS flow forward on another port than 80).
