Somehow one of your your default system font has become corrupted 
probably the "Times" instance. You can often fix this by examining the 
font in Font Book.app. You often find that there is a duplicate instance 
of a system installed font and that deleting the offending instance 
withing Font Book.app will cure the problem. Look  first at the "serif" 
entry to postscriptFonts():

names( postscriptFonts() )

postscriptFonts()[ "serif" ]
