hexbin runtime warnings

Any idea what could cause hexbin to issue runtime warnings and then draw
a blank figure?

/home/nbecker/.local/lib/python3.3/site-packages/matplotlib/axes.py:6524:
RuntimeWarning: invalid value encountered in true_divide
  x = (x - xmin) / sx
/home/nbecker/.local/lib/python3.3/site-packages/matplotlib/axes.py:6539:
RuntimeWarning: invalid value encountered in less
  bdist = (d1 < d2)

Not sure. Can you provide a small, standalone example that reproduces the problem?
