Describe the issue

Just a place for me to track these so that I know which are expected and which are due to my own mistakes.

Summary

On master, building the docs on the latest arch using a fresh install of Miniconda produces the following warnings

generating gallery for gallery/subplots_axes_and_figures... [ 73%] secondary_axis.py
/home/bbeltr1/developer/matplotlib/examples/subplots_axes_and_figures/secondary_axis.py:65: RuntimeWarning: divide by zero encountered in true_divide

In addition, findfont fails on the following (even though I have all these fonts installed). Presumably though, this part is my own fault.

The unchained.py example still emits this warning, and takes a ton of time despite not having much apparent detail. Also why is it all-caps?

I'm working with sphinx-gallery to improve the situation here.
