XGetImage didn't generate the error, XCreatePixmap did.
You are forgetting the client-server model. The server didn't
get the CreatePixmap until you made your GetImage request,
which would flush requests to the server (necessary since
GetImage requires a reply from the server). Call XSync after
your XCreatePixmap and you'll see it fail then.
