genPreviewGen in databook.re fired for unprocessable file types?

[michael-conway]

databook.re contains this stanza

postProcForPut {     
        on(include($objPath)) {
                postProcForCreateCommon($objPath, $dataSize, true);
                # preview must be generated after the file is uploaded
                # genPreviewGen($objPath, *previewThumbPath, *previewPath);
        }
        or {
                succeed;              
        }
}

And genPreviewGen needed to be commented out otherwise it threw errors for files like PNG and jpg

      }
