[Kwant-devel] Plotting to PDF broken with matplotlib 1.3.1

While building kwant 1.0.4 packages for Ubuntu, I noticed that the 
documentation does not build on Ubuntu 14.04, the current LTS 
version: [1].  It’s due to the plotting scripts failing to run.

I can reproduce this problem on a VM that runs Ubuntu 14.04.  It 
seems to be due to a commit [2] by Michael that fixes plotting for 
matplotlib >= 1.4.0.

I think we should fix this to keep Kwant working well on current 
Ubuntu LTS as well.
Do the matplotlib experts among you see a way to fix this other 
than having different code paths for different matplotlib
