[Tilecache] Labels getting cut at tile boundaries

[David Alda Fernandez de Lezea]

Hi list,

I'm facing a little problem with some labels from a layer that I've generated with tilecache. They're splitted in the tile boundaries. I've been reading some solutions. I've succesfully installed Python Imaging Library, and I've also set metaTile=true and metaBuffer=256, but when I execute tilecache_seed.py over this layer I get an error:

My layer configuration at TileCache

[toponimia_50000]
type=WMSLayer
layers=toponimia_50000
srs=EPSG:23030
maxResolution=292.96875
bbox=460000, 4690000, 610000, 4820000
url=http://192.168.1.38/cgi-bin/mapserv.exe?map=../htdocs/ogcservices/wms/wms.map&TRANSPARENT=true
extent_type=loose
extension=gif
metaTile=true 
metaBuffer=256

Do I have to configure something else??
 
Thanks in advance.
 
Un saludo,
