They can be triggered by telling the postscript driver to load an afm file
that doesn't exist, e.g. :

postscript(family=c(doesnotexist1.afm, dne2.afm, dne3.afm, dne4.afm ), etc)

To trigger the problem with the pdf and xfig drivers, remove one of the
afm files from R's afm directory, e.g. hv______.afm and then use
family="Helvetica" in the pdf or xfig driver.
