Hello,

your package registers some fonts like fcyr.gsf as type1 via defoma but
t1lib1 is not able to read that files. Due to Evgeny Stambulchik
<fnevgeny@plasma-gate.weizmann.ac.il> (the upstream maintainer of the
grace package) that font is missing the mandatory "%!PS-AdobeFont-1.0"
header. You can test t1lib with the command

xglyph /usr/share/ghostscript/fonts/fcyr.gsf

and click 'Font Table'.
