GetFeature request fails through proxy for layernames with spaces

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Create a layer with a space in its name on a WMS service hosted on a 
different domain to the AtlasMapper. This will result in the GetFeature 
requests being made through the proxy.
2. Add the layer to a map and click on a feature, observing the network 
traffic. The layer name gets truncated at the space in its name resulting in 
the GetFeature request failing.

What is the expected output? What do you see instead?
The proxy on the server should issue the feature request with the full layer 
name. Instead it is truncated which can be seen in this example error response 
to the feature request for the layer "aims:AIMS - Weather Station":

 <?xml version="1.0" encoding="UTF-8" standalone="no"?><!DOCTYPE ServiceExceptionReport SYSTEM "http://maps.aims.gov.au/geoserver/schemas/wms/1.1.1/WMS_exception_1_1_1.dtd"> <ServiceExceptionReport version="1.1.1" >   <ServiceException code="LayerNotDefined">
      Could not find layer aims:AIMS
</ServiceException></ServiceExceptionReport>

What version of the product are you using? On what operating system?
Version 1.3, Linux
