Description of problem:

When inserting a math formula object (or creating a new formula
document), a rectangle is rendered instead of minus operator.

Steps to reproduce the bug:



Version-Release number of selected component (if applicable):

OpenOffice.org 2.0.2 (core package, not updated)

How reproducible:

1) New document
2) Insert->Object->Formula
3) Type an expression, e.g.  a-b=5
