Accented characters in Cambria and math

[zhoraster]

The problem occurs when an accented character in Cambria is used with maths in another font in the same paragraph. Here is the minimal example:

\documentclass{minimal} 
\usepackage{fontspec}
\setmainfont{Cambria}
\begin{document}
й $xy$
\end{document}

The compilation stops and the error is following:

error: ...s/MiKTeX 2.9
/tex/luatex/luaotfload/otfl-node-inj.lua:225: attempt to index local 'tm' (a nil
value)
.
\newpage ...k \@nobreakfalse \everypar {}\fi \par
                                              \vfil \penalty -\@M
l.6 \end{document}

When they are in different paragraphs e.g. the document body is

\begin{document}
й 

$xy$
\end{document}

then there is no problem. Also there is no problem as well if I use the same math font e.g. with

\usepackage{unicode-math}
\setmathfont{Cambria Math}

But still the compilation stops if I use a symbol from a different font (e.g. \Box from amssymb).

UPD: Happens only if Cambria Regular is taken from Cambria.ttc file containing both Cambria Regular and Cambria Math.
