[Tilecache] Tilecache.cgi works fine, tilecache_seed.py bombs...

[Steve Lime]

Hi all: I've got tilecache working fine via the CGI script and am moving on to seeding the cache. My setup is a mapserver
mapfile will all default layers. The following config is working:

[compass]
metaTile=true
type=MapServerLayer
layers=
mapfile=/usr/local/www/docs_maps/compass/compass.map
levels=12
srs=EPSG:29615
bbox=105000,4785000,809000,5489000
maxResolution=5500
extent_type=loose

However, running the seed script like so:

./tilecache_seed.py http://maps.dnr.state.mn.us/tilecache/tilecache.cgi compass 0 11

flames out with:

###### (0, 0, 0), (1, 1, 0)

I'm not sure why the config works in one case but not in another, other than it must have to do with an empty layer list. The URL in the error snippet does return a valid image. Ideas?

Thanks - Steve
