This is why I filed #662892 against ghostscript rather than octave or
gnuplot. Some combination of ghostscript and the Pagul font is causing
an error in the ghostscript routine that looks up TrueType fonts by
name.
That is only the place where the two errors become visible. The other
error is in Octave IMHO, since it also should not set an invalid font as
default. If it is allowed by the PostScript specification it would still
be not a good programming style.
