[Tilecache] Tilecache Seeding using Point/Radius

[JP de Miranda]

I'm trying to use the tilecache_seed with a point and radius, but no 
matter what point and radius I provide the seeding stops at level 16

I'm using these settings in my cfg
[ORN]
type=MapServer
mapfile=/var/www/html/wms/map_file/mymap.map
extension=png
layers=ORN
srs=EPSG:900913
bbox=-20037508.3427892,-20037508.3427892,20037508.3427892,20037508.3427892
metaTile=true
metaSize=12,12
metaBuffer=10
extent_type=loose

With the following commands
./tilecache_seed.py "http://localhost/tilecache/tilecache.cgi?" ORN
-8848465.85,5456040.48,10000
./tilecache_seed.py "http://localhost/tilecache/tilecache.cgi?" ORN
-8848465.85,5456040.48,20000

When I provide a bounding box for the same area I'm able to seed all the 
way to level 19 with the following command
/tilecache_seed.py "http://localhost/tilecache/tilecache.cgi?" ORN 10 20 
"-8841517.76,5408424.01,-8832933.58,5419334.22"

Is there a problem in the way I'm launching the script or is there a 
problem in the script?

Thanks for you help
