There is no creator set:

And if it would contain a creator, why would DT then show an empty creator in 
the GUI? 

And the interesting thing is also that for the G9XII the creator section in the 
xmp file does not exists, as mentioned. But for the 20D RAW the xmp file 
contains an empty section:
   <dc:creator>
   </dc:creator>

And this is shown in the GUI as "unknown" creator. The correspondig 20D RAW 
fiel has similar exiv2 info:
