Trouble with recent mpl

Hi all,

I rerun a program which I have written one year ago.
Now It doesn't work for me with the latest svn version.
Here is the output
python lshape.py --verbose-helpful

Hi Nils,

It seems there's a problem with some of the text instances (label,
title etc.) that have TeX expressions in them.

You can also attach the problematic script (or part of it) here.

Best,
Edin
