In case someone out there is stuck real bad with this bug in bookworm, here's a very nasty workaround for which I of course decline all responsibility:
$ mkdir /usr/share/fonts/type1/gsfonts $ ln -sf /usr/share/fonts/X11/Type1/C059-Roman.pfb /usr/share/fonts/type1/gsfonts/n021003l.pfb Cheers, -- Seb
