Howdy,

Could be your version of `Linux Libertine O' or, maybe your version of fontspec? I'm on TL2010 (via MacTeX install) with all updates (via tlmgr via TeX Live Utility) and have

I'm using the latest Linux Libertine O (again all updates via...) found in 

.../texmf-dist/fonts/opentype/public/libertine/

e.g., v 4.8.7 of the ``regular'' font.

Good Luck,
