libcdio 1.2.1 has been marked unstable for a long time, and it has many advantages over 0.9.5, namely UTF-8 support.
I'd just like to add that it has been stable for me on amd64.
Care to show me where's that version? http://sources.gentoo.org/viewcvs.py/gentoo-x86/dev-libs/libcdio/ http://ftp.gnu.org/gnu/libcdio/
