1. $ md5sum /usr/share/texmf/fonts/type1/public/lm/lmr10.pfb f35b44530a1d90eb90fe15d9cba67ea0 /usr/share/texmf/fonts/type1/public/lm/lmr10.pfb
2. I reinstalled lmodern package. Same result. Recent versions of gs removed a lot of gs extensions to get closer to standard postscript and for some security issues, so that's probably the root cause but gsftopk probably ought to detect that and at least give a sensible error. -igor
