In case you are referring to xdg-mime from the xdg-utils package, it does 
whatever the running desktop's utility does :)

So I guess gnomevfs-info will query mimeinfo.cache and related files, while 
kfile uses KDE3's MIME lookup mechnism, which is pretty sure not using 
mimeinfo.cache yet but rather files stored in KDE's mimelnk directories (see 
kde-config --path mime)
