I want to plot a bar graph which contain some nan values and save it to PDF. If I open the file in evince it shows several errors like "Syntax Error (596): No current point in closepath" on the console but plot is shown as expected. This only happens with the pdf backend, cairo pdf backend works. I think this is related to #3654.

I'm on Matplotlib 1.5.1 (installed via pip), python 2.7.6, Linux

Example code:

#!/usr/bin/env python

import matplotlib.pyplot as mpl

fig = mpl.figure()
ax = fig.add_subplot(111)
bars = ax.bar([1], [float("NaN")], 0.2)
mpl.savefig("test.pdf")
