Weird, because in my desktop(Debian 4.0) with the same configuration
works and in the server(Ubuntu Dapper) not.

My tilecache.cfg
[cache]
type=DiskCache
base=/var/www_django/maps/tilecache/cache

[continente]
type=MapnikLayer
mapfile=/var/www_django/maps/tilecache/ptx-osm-2.xml
bbox=-11.535,36.095,-4.535,43.095
maxResolution=0.015693359375
levels=12
extension=png
srs=EPSG:4326
debug=on
metaTile=yes
metaBuffer=40

the url is:
/?LAYERS=continente&FORMAT=image%2Fpng&SERVICE=WMS&VERSION=1.1.1&REQUEST=GetMap&STYLES=&EXCEPTIONS=application%2Fvnd.ogc.se_inimage&SRS=EPSG%3A4326&BBOX=-7.5175%2C36.095%2C-3.5%2C40.1125&WIDTH=256&HEIGHT=256
