Islands not rendering in Osmarender

Hi

Can somebody explain me why my islands around Dakar, Senegal doesn’t show up in Osmarender?
(http://www.openstreetmap.org/?lat=14.75464&lon=-17.51053&zoom=16&layers=0B0FTF)

Differences to some island in the North sea is that I didn’t use the layer tag. Is this necessary? Or is this another case of “tagging for the renderer”?

There’s an email message from Frederik Ramm in the T@H mailinglist where he mentions problems with islands and that he’s working on it. So I guess with a bit of patience things might turn out allright.
