Duplicate Properties and Line Encodings

What steps will reproduce the problem?
1. Point to WSDL: 
https://technet.rapaport.com/webservices/prices/rapaportprices.asmx?wsdl
2. Generate Code

What is the expected output?

The generated code duplicates the declaration of 
RapaportPrices_AuthenticationTicketHeader in multiple places.  I haven't 
determined why based on the WSDL.

@interface RapaportPricesSoap_GetPriceChangesTest : RapaportPricesSoapOperation 
{
    RapaportPrices_GetPriceChangesTest * parameters;
    RapaportPrices_AuthenticationTicketHeader * AuthenticationTicketHeader;
    RapaportPrices_AuthenticationTicketHeader * AuthenticationTicketHeader;
}
@property (retain) RapaportPrices_GetPriceChangesTest * parameters;
@property (retain) RapaportPrices_AuthenticationTicketHeader * 
AuthenticationTicketHeader;
@property (retain) RapaportPrices_AuthenticationTicketHeader * 
AuthenticationTicketHeader;
- (id)initWithBinding:(RapaportPricesSoap *)aBinding 
delegate:(id<RapaportPricesSoapResponseDelegate>)aDelegate
    parameters:(RapaportPrices_GetPriceChangesTest *)aParameters
    AuthenticationTicketHeader:(RapaportPrices_AuthenticationTicketHeader *)aAuthenticationTicketHeader
    AuthenticationTicketHeader:(RapaportPrices_AuthenticationTicketHeader *)aAuthenticationTicketHeader
;
@end

The app refuses to compile do to this and also Xcode 4 preview 5 (running Lion 
but also tested on Snow Leopard with Xcode 4) gives the following error that 
appear to be do to injected line encodings:

@property (%«element.type.assignOrRetain» *** ERROR: undefined key *** ) 
%«element.type.classNameWithPtr» *** ERROR: undefined key ***  
%«element.name» *** ERROR: undefined key *** ;

This appears to be an error resulting from the code generation.

What version of the product are you using? On what operating system?

I've tried both the current release and the 0.7 pre-release.  I've tested on 
Mac OS X Lion Preview 3 and the most recent build of Snow Lepoard.  I'm 
compiling to the iOs 4.3
