invalide extension in the wms capability file

[Chris Tweedie]

Rainer,

try adding the wms_extent parameter to your LAYER / METADATA object.

This will override the need for MS to try and determine the extents 
from PostGIS, i have had some occasions where the BBOX was reported 
incorrectly (especially from postgis/sde). Just make sure what you 
specify is in the correct SRS.

eg.
LAYER ..
METADATA
wms_extent "2000073 5310090 3001881 6785641"
