I get the same thing with master on 64-bit ubuntu natty, but not with 
v1.1.x. Mike did quite a bit of work on src/_png.cpp between those two. 
 The most recent commit to that file is not causing the problem, but I 
have not tracked it down beyond that.

Tried using plt.imread() today on a PNG file, and I am getting this PyCXX
error:
Traceback (most recent call last):
 File "<stdin>", line 1, in <module>
 File "/home/ben/Programs/matplotlib/lib/matplotlib/pyplot.py", line 1746,
in imread
 return _imread(*args, **kwargs)

in imread
 return handler(fd)
TypeError: PyCXX: Error creating object of type N2Py6ObjectE from (nil)
Using master branch on Python 2.7 on 32-bit Ubuntu Oneric. Seems to happen
to both color and b&w images. scipy.ndimage.imread() still works fine,
though.
