You might just be tickling the segfault you reported earlier (which appears to happen [sometimes] when R cannot find the AFM files). Try ...

afmfiles <- c("/usr/share/texmf/fonts/afm/yandy/lubright/lbr.afm",

               "/usr/share/texmf/fonts/afm/yandy/lubright/lbd.afm",
               "/usr/share/texmf/fonts/afm/yandy/lubright/lbi.afm", 

               "/usr/share/texmf/fonts/afm/yandy/lubright/lbdi.afm",
               "/usr/share/texmf/fonts/afm/yandy/lubright/lbms.afm")
