RHN applet not working

[Jaap A. Haitsma]

I upgraded to the latest up2date but it seems that there is still 
something missing in de Fedora Core and Updates repository

RHN applet doesn't show that there are updates, whilst there are.
It returns the following information

The applet has been unable to access the following information sources 
in its last attempts: fedora-core-1 @ 
http://fedora.redhat.com/releases/fedora-core-1, updates-released @ 
http://fedora.redhat.com/updates/released/fedora-core-1
