The problem was that matplotlib requires wx2.8, but on debian when
both 2.6 and 2.8 are installed, 2.6 is chosed. I sent a patch upstream
to convert to "import wx" together with a way to choose wx2.8 (using
wxversion)

with wx2.8 it works as expected.

That's what the patch I forged do. I attached here too, just in case
you want to look at and apply it locally.
Anyhow, I don't plan an upload to just fix these examples, so this bug
will be fixed when upstream will release a new version.
