Here's a curiosity. I played around with your example using my AlphaPC running Debian. I get the same results as you with both Python 2.2 and 2.3. However, I noticed a trick. I have no idea what's going on, but maybe it's a workaround.
When I run this, everything seems to work OK:
import Image
im = Image.open('title.png')
im2 = im.copy()
im2.verify()
im3 = im2.copy()
I haven't played around much with it, but maybe that can lead to a workaround for you until a real solution gets posted.
