[Tilecache] Problem with tilecache_seed.py

[Alexandre Dube]

Well, I'm back with more problems.

  The script stopped running after more than 12 hours.  I'll try to test 
with different type of data ( shapefiles, using gif, metaTile, 
MapServerLayer type ) locally to see if theses errors ( everyones I 
faced so far) occur.

Here's was the content of the .cfg file :

[raster]
#type=MapServerLayer
type=WMS
layers=mos,img
#mapfile=/home/mapgears/proj/toto_test/map/toto.map
url=http://127.0.0.1:8080/cgi-bin/mapserv?map=/home/mapgears/proj/toto_test/map/toto.map
extension=jpg
srs=EPSG:32187
resolutions=35.27775872778806,17.63887936389403,8.819439681947015,3.527775872778806,1.763887936389403,0.8819439681947016,0.35277758727788067,0.17638879363894033,0.08819439681947017,0.035277758727788065
bbox=189653.232384,5373969.71,231271.235,5402372.275
#metaTile=true

Here's the error :
