When I hit walls like this with WMS services, as painful as it may 
sound, I manually write the full request in the browser, and check the 
response there (if you have trouble writing all the parameters, you can 
check your Apache logs or QGIS logs for the full request).  That way you 
take out any other possible software problems (such as clients like QGIS).
