Dear Charlie:
For my case, frame 57 is wrong and also some after 57.
I think it's a known issue bcz so many tools(Include ACDSee) got same
problem. Maybe IP reasons.
I will try on MacOS.
Also thanks for your advice to be more Pythinic. :P
Br,
Lixin Song

The problem seems to be related to the underlying library used for either
GIF or PNG images as your script runs fine on my machine (Mac OS 10.7).
Frames 2 and 56 look a bit weird but the original image looks like this.
I'm not sure which frames you think don't work.
FWIW your script isn't very Pythonic (the try clause should preferably
only contain one statement with known error conditions) and can be
rewritten thus:
for i in range(im.info['duration']):
try:
im.seek(i)
except EOFError:
break
im.save("test%02d.png" % i)
