Hi Michael, thanks for testing!

Fractions and text figures (onum) appear to be mutually
exclusive. Test for plain:
\input luaotfload.sty
%\font\libertineregular="name:Linux Libertine O:+frac;+onum" \libertineregular
\font\libertineregular="name:Linux Libertine O:+frac" \libertineregular
foo 1/2 \quad 1/5 \quad 355/530 \quad bar
\bye
And latex/fontspec:
\documentclass{article}
\usepackage{fontspec}\setmainfont{Linux Libertine O}
\begin{document}
{\addfontfeature{Fractions=On}
+onum: 1/2 \quad 1/5 \quad 355/530 \quad}\endgraf
{\addfontfeature{Fractions=On,Numbers=Lowercase}
+frac;+onum: 1/2 \quad 1/5 \quad 355/530 \quad}\endgraf
\end{document}

Not really. But judging from your logs your luatex binary is
*really* out of date. There’s even warning:
Module luaotfload warning: LuaTeX v0.70 is old, v0.76 is recommended.
The font loader relies on Luatex features like node.end_of_math()
so it is likely to break with your binary. Are you certain that
you did a complete update?
Best
