Well, I got quite confused with this behaviour too. Obviously the equation
editor doesn't take standard LaTeX but some variant called "iTeX".
Googling that yields http://pear.math.pitt.edu/mathzilla/itex2mmlItex.html
for example.
So an matrix-equation is written this way:

J_{Pol}^R = \left[ \array{\epsilon_R & c_{Ry} \\ c_{Rx} & \tau_R} \right]
\approx \left[ \array{\epsilon_R & 0 \\ 0 & \tau_R} \right]

This example works in my version of AbiWord. So try this to check that
your installation works correctly. (Note: Probably the Epsilon won't be
displayed correctly - that's a known bug which will be hopefully be fixed
soon.)
Unfortunately AbiWord always gives the general error message you wrote
above and never a detailed description of what went wrong. So I suggest
playing with small equations first and after you get used to it, te
equation editor is a handy tool to use.

Hope this helps,

Dirk
