It is an error, the map does not show up. It does not matter if I add  
this as the first or last layer to my map.

The following data-set used to show up in may, but not now. I know  
this as we tell people to use this as the background map for our WMS  
project. We could of course tell them to use a world dataset with  
a .prj-file if I could find one..
