I am trying to serve up a GeoTIFF via TileStache using the Mapnik provider, and am getting only black tiles. The TileStache folks say that this seems to be an issue with Mapnik.

This is the Mapnik package in the Ubuntu karmic 9.10 repositories: libmapnik0.6, /usr/lib/libmapnik.so.0.6.1 mapnik.mapnik_version() returns "601"

One of the specific TIFFs can be had here. It opens fine in qGIS, I doubt it's the problem.

My Mapnik mapfile is as follows. It includes a few other files for database settings, zoom level definitions, etc. THey may not be relevant but I can provide them as needed.
