[Tilecache] tilecache_seed.py making duplicate mapserver requests?

[Russell McOrmond]

   We are trying to seed at 5 different resolutions, and noticed something 
odd.   For the first 4 resolutions tilecache_seed.py requests the same 
image from mapserver 4 times.  For the 5'th resolution it requests 
different images.   I'm wondering what might be happening, and whether 
this is a bug or a configuration error.

Relevant lines from configuration:


[DEFAULT]
type=WMS
extension=png
debug=no
srs=EPSG:42304
bbox=-2903297,-789911,3431059,3959683

extent_type=loose
metaTile=yes
metaSize=20,20
metaBuffer=20
url=http://mapserver/ogc/phz-zrp_wms_en

#Plant Hardiness Zones of Canada
[phz-zrp_wms!PlantHardinessZone]
layers=PlantHardinessZone5-50M,PlantHardinessZone1M


I'm using the following call to tilecache:

./tilecache_seed.py phz-zrp_wms\!PlantHardinessZone 0 6 -b "-2903297,-789911,3431059,1412914"

Thanks.
