Alan, I can confirm that the special definefont line ">> definefont" does not appear in my Ubuntu generated plots. I do not have access to the debian testing plots here at home to check them I'm afraid. I can confirm that I did not see any errors with gv --noquiet on these plots though. Since the cairo version we are using should be the same, then the only difference I can see is the installed fonts.
