It's  Windows-specific and easy to fix: replace

    cmd <- paste(gsexe, " -dNOPAUSE -dBATCH -q -sDEVICE=", type,
                 " -r", res,
                 " -g", ceiling(res*width), "x", ceiling(res*height),
                 " -sOutputFile=", file, " ", tmp, sep="")

by

    cmd <- paste(gsexe, " -dNOPAUSE -dBATCH -q -sDEVICE=", type,
                 " -r", res,
                 " -g", ceiling(res*width), "x", ceiling(res*height),
                 " -sOutputFile=", file, sep="")

Fixed for 1.2.3
