Bug Report - tex2ooo

Using Maxima 5.15.0, compiled on Debian Lenny AMD64 using CLISP.

kill(all);
(%o0) done
(%i1) load (tex2ooo);
(%o1) /usr/local/share/maxima/5.15.0/share/contrib/tex2ooo.lisp
(%i2) 'integrate(x^2*exp(-%i), x);
(%o2) %e^(-%i)*integrate(x^2,x)
(%i3) tex(%);
Maxima encountered a Lisp error:

APPEND: A proper list must not end with " cdot "
Automatically continuing.
To reenable the Lisp debugger set *debugger-hook* to nil.

(%i2) (s+1)/(s^4+3*s^3+4*s^2-2*s-3);
(%o2) (s+1)/(s^4+3*s^3+4*s^2-2*s-3)
(%i3) tex(%);

BTW: "cdot" is multiplication "." in OOoMath.

Thanks
