I must not be understanding you correctly.
If the parent terminal was closed, how could you see these error messages?
What do you mean by "parent terminal"?

It may be possible to get this error if the current terminal is very small
("terminal" in the gnuplot sense of "set terminal ... size XX,YY"),
although I couldn't trigger it by intentionally setting the x11 window to
as small as it would go by resizing with the mouse.  Instead I saw warnings
like "Warning - difficulty fitting plot titles into key" and 
"warning: difficulty making room for xtic labels".
Did you see this kind of message also?
