[Tilecache] Problem with spherical mercator at one zoom level

I'm experiencing a strange error with TileCache rendering labels with
Mapnik and a point shapefile. For zoom level 1 only labels on the
southern hemisphere (the two bottom tiles) are rendered - see the
image attachment on the link above. The other zoom levels are rendered
correctly. It works when using standard latitude/longitide projection
(EPSG:4326), but not "spherical mercator".

Is this an issue with TileCache?

Cheers,
Bjørn
