HTLoadToChunk problem

I'm having trouble using HTLoadToChunk - hopefully I'm simply using it 
incorrectly. For some reason when I call HTLoadToChunk to retrieve a 
data file (for example a GIF) it wants to dump the data to a file 
rather than to the chunk.

The following test program shows that the returned chunk exists but 
chunk->data does not. Along the way, it prompts for a filename and 
successfully saves the GIF to a file. I want the GIF to be kept in the 
memory chunk. Am I doing something wrong?

#include "WWWLib.h"
#include "WWWInit.h"
#include "WWWApp.h"

int main (int argc, char **argv)
{
    HTProfile_newPreemptiveClient ("Test", "1.0");
        {
        HTRequest * req = HTRequest_new ();
        HTChunk * chunk = HTLoadToChunk 
("http://home.netscape.com/images/noscript_banner.gif", req);

        if (chunk)
            {
            printf ("Chunk exists\n");
            if (chunk->data)
                printf ("Data exists\n");
            }
        }

    return (0);
}

This problem occurs on both NT 4.0 and BSDi 1.1 compiles of libwww. 
Any URL gives the same behavior.
