Hi,

The following code causes matplotlib to hang:

## ···

---

import numpy as np

import matplotlib as mpl

mpl.use('Agg')

import matplotlib.pyplot as plt

from matplotlib.patches import Circle

fig = plt.figure()

ax = fig.add_subplot(1,1,1)

ax.add_patch(Circle((1.e17, 1.e17), radius=1.e15))

fig.savefig('test.png')

---

Am I doing something wrong?

Thanks for any help,

Cheers,

Tom
