cut with np.inf gives TypeError

[DanielWeitzenfeld]

import pandas as pd
import numpy as np
arr = np.random.randn(20)
factor = pd.cut(arr, [-np.inf, 0, np.inf])

gives this error:

Traceback (most recent call last):
File "", line 1, in

TypeError: %d format: a number is required, not numpy.float64

I'm using pandas version 0.12.0. Removing the -np.inf and np.inf eliminates the error.
