Hello David, sorry for the delay.
The problem is caused by \frac being defined in the newmat
module as
%D Better:
\def\frac#1#2{\mathematics{\genfrac{}{}{}\donothing{#1}{#2}}}
If you comment that line, it will compile flawlessly.
Hans, why would you want to allow \frac in text mode?

(Yes.)

Yup, I just changed a couple of things and now we have a
\startbigcases ... \stopbigcases for this. Will upload new
version soon.
