[Image-SIG] PNG Support with Parsed images.

If I load a png file with Image.open, I can manipulate it, save it
etc. If I however use ImageFile.Parser(), I can read the size, format
and any info, but I can't show or manipulate the image in any way.
I get this exception on any of the requested methods:
Here is what I'm typing:
>>> import ImageFile
Traceback (most recent call last):
File "<stdin>", line 1, in ?
File "/usr/lib/python2.4/site-packages/PIL/Image.py", line 1449, in show
_showxv(self, title, command)
File "/usr/lib/python2.4/site-packages/PIL/Image.py", line 2082, in _showxv
file = image._dump(format=format)
File "/usr/lib/python2.4/site-packages/PIL/Image.py", line 476, in _dump
File "/usr/lib/python2.4/site-packages/PIL/ImageFile.py", line 189, in load
s = read(self.decodermaxblock)
File "/usr/lib/python2.4/site-packages/PIL/PngImagePlugin.py", line

File "/usr/lib/python2.4/site-packages/PIL/ImageFile.py", line 300, in read
data = self.data[pos:pos+bytes]
TypeError: unsubscriptable object
This is with version 1.1.6. I double checked 1.1.5 and got the same thing.
This works fine with a JPEG image. The PNG support appears to have a
bug to me, but perhaps I'm missing something.
