> Guacamole's VNC implementation assumes that the {{rfbClient}} object will be available
at the time that keyboard or mouse events occur, but this is not guaranteed. That object will
only be available once the VNC connection process has completed.
> Thus, if keys are pressed while the connection is not yet ready, the event handler tries
to send a key event to {{NULL}}, a segfault occurs, and the Guacamole connection closes.
