Neither. The error comes from any X client I try to run
under an ssh -X command started from inside the VNC session.
The X clients all error off trying to talk to the forwarded
X display connection. If I provide them with the direct
DISPLAY="vnchostname:1" and run xhost + to allow connections
inside the VNC session, then the X clients work fine.
