I can confirm this bug. I have the same config. I encountered the same issue. I ran the dbus-send commands indicated here for diagnosis and had the same UnknownMethod error message.
A thread on liferea-devel suggests to me that this is due to a mismatch between liferea and the 1.0.1 version of gwget we have on ubuntu 9.04. It used to be working with an older version of gwget (a pre 1.0 version).
