Hello, Sandro,

Unfortunately the problem had been solved. Analysis showed the
matplotlib didn't like a font installed into ~/.fonts (actually not the
font itself but its description in ~/.fonts/font.map and fonts.dir).
For now I don't need that font. After removing it everything had been
worked. However, it is not good for library to crash if some
third-party data is malformed in its opinion, especially when all other
programs dealing with the fonts work fine.
