This is a bug somewhere that is trying to set a property on a non-existent
QPainter. That might be tricky to track down. Doesn't seem to be hurting
anything, though.

This is a system-installed module (not part of the QGIS packaging). You can
just ignore the warning.

You could try the following to get rid of the warning:

sudo touch /System/Library/Frameworks/Python.framework/Versions/2.7/
Extras/lib/python/mpl_toolkits/__init__.py

Just creating a blank __init__.py may do the trick. However, due to SIP
security on 10.11.x , you may not be 'allowed' to create the file (even
with sudo). If so, you can temporarily turn off SIP, create the file, test,
then turn SIP back on [0].

Alternatively, you could try installing matplotlib Python package from
Kyngchaos.com or the official package somewhere on sys.path that will be
picked up before the system install of matplotlib. I don't think this will
really get rid of the warning, which may happen whenever the system paths
are parsed.
