Any idea what that is?
I haven't the faintest idea. The function seems to be called with a "None"
font, and then it crashes. As it's executed under a Linux system it uses
the fontconfig backend with cairo. The call only occurs when matplotlib is
fed more data than can be isolated in an simple example
