I tested it under Linux now, and I see your problem. The latex files don't
compile cleanly, this is why you get the
error. You can find the .tex files under ~./matplotlib/tex.cache
It looks like you have a problem with the font encoding when using unicode
characters.
This works for me under Linux and Windows:
import numpy as np
import matplotlib as mpl
mpl.rcParams['text.latex.preamble'] = [r'\usepackage{amsmath}' ,
r'\usepackage[T1]{fontenc}']
mpl.rcParams['text.latex.unicode'] = True
mpl.rcParams['text.usetex'] = True
import pylab as py
py.axhspan(8400,8730,alpha=0.15)
py.title(u'Wyniki eksperymentu pomiaru gęstości ciała
stałego',size='large',family='serif')
py.ylabel(r'$\text{lol}$',size='large',family='serif')
py.grid(True)
py.show()
