While libbinio is installed, a corrupt entry is present in top dir of info - an entry of unprintable chars. The fix is actually in cvs, but was never released. http://libbinio.cvs.sourceforge.net/viewvc/libbinio/libbinio/doc/libbinio.texi?r1=1.13&r2=1.14 The fix is obviously that '.' after ')'.
Fixed in CVS. Thanks for reporting!
