st: eps set fontface command

["David LB Schwappach" <dlb@h-ero.de>]

Dear all,
I'm having trouble using the fontface option with the graphs set
command:
. graph set eps fontface times
returns
"" required
r(198);

(this error code is returned whatever font I specify)

Any help would be very appreciated.
Thank you
David
