[Tilecache] Help with tilecache UTM layer

[Mike Meier]

Hi,

i have problems to get the tilecache work with a WMS Layer in EPSG 25833 
( ETRS89 / UTM zone 33N)

is use tilecache 2.03, Debian etch, Python 2.4

The tilecache-URL
"http://172.16.1.8/tilecache/tilecache.py?SERVICE=WMS&VERSION=1.1.1&REQUEST=GetMap&FORMAT=image/png&TRANSPARENT=TRUE&LAYERS=basic&STYLES=&SRS=EPSG:25833&BBOX=365568.000000,5812224.000000,366080.000000,5812736.000000&WIDTH=256&HEIGHT=256"
gives me the result : "An error occurred: Currentt x value 365568.000000 
is too far from tile corner x 365376.000000"

The real WMS URL
http://172.16.1.8/cgi-bin/mapserv?map=/var/src/mapserver-5.0.1/tests/feuer-dop-jpg.map&SERVICE=WMS&VERSION=1.1.1&REQUEST=GetMap&FORMAT=image/png&TRANSPARENT=TRUE&LAYERS=dop&STYLES=&SRS=EPSG:25833&BBOX=365568.000000,5812224.000000,366080.000000,5812736.000000&WIDTH=256&HEIGHT=256
gives me a image.

Layer.py:
         if (abs(minx - tilex)  / res > 1):
                raise TileCacheException("Currentt x value %f is too far 
from tile corner x %f - z %f res %f - %f" % (minx, tilex...

The "abs(minx - tilex)  / res" results is 96.

config:

[basic]
type=WMS
srs=EPSG:25833
layers=dop
url=http://172.16.1.8/cgi-bin/mapserv?map=/var/src/mapserver-5.0.1/tests/feuer-dop-jpg.map?
extension=png
resolutions=6,4,2,1,0.5,0.1,0.05,0.025,5.906250,13.718750
size=256,256
levels=15
bbox=200000.0,5600000.0,500000.0,5970000.0
maxresolution=2000000.0
units=meters

If I change the srs parameter to 4326 or to 25833, nothing happens.

dont work for me.
