DataFrame construction breaks python on numpy empty_like
#### Code Sample, a copy-pastable example if possible

http://stackoverflow.com/questions/39129419/why-does-dataframe-construction-break-python-on-numpy-empty-like

```
import numpy as np
import pandas as pd

a = np.array([None, None], dtype=object)
print(a)      # [None None]

dfa = pd.DataFrame(a)
print(dfa)

#      0
#0  None
#1  None

b = np.empty_like(a)
print(b)

#[None None]

(a == b).all()

#True

dfb = pd.DataFrame(b)  # Fine so far
print(dfb.values)

#[[None]
 #[None]]

print(dfb)  #Crash
```
#### Expected Output
#### output of `pd.show_versions()`

```
