Comment:

 Yahoo messenger does not let the user save the buddy icon but you can
 access the cached icons inside C:\Program
 Files\Yahoo!\\Messenger\Cache\Icon. All icons are there are identical with
 the ones saved by pidgin.

 I've used pngcheck in order to check the png files and it seams that the
 problem is related to zlib decompression. I'm almost sure that Y! is not
 going to repair this because their png decompresser is able to handle with
 the problem like libpng. Still this does not makes the files valid png
 files and people saving files will wonder why they see garbled images.
