[mapserver-users] msWMSLoadGetMapParams(): WMS server error.

[James Perrins]

Not quite sure of your setup - but can you use something like firebug
in firefox - of maybe fiddler (though you would have to send your call
via its proxy) - to see the actual call being sent to mapserver

I think thats what I'd try as the only thing I can think of is
OWSRequest is mangling the call in some way.  Seeing what its actually
sending might give you a clue ...
