[Image-SIG] GIF frame extraction problem

[Pier Paolo Glave]

Hello,

I'm using PIL version 1.1.3 to manage animated GIFs, and I'm facing a 
problem with the GIF image that you can find at this web address:
http://digilander.libero.it/pglave/sole24oreabbonamento.gif

The image is a sequence composed of 12 frames.
The problem is that PIL sees as "black" the last four frames of the 
sequence.
Other players, such as Netscape or Internet Explorer, correctly show all 
frames, including the last four.

Can you tell what could be the problem with this GIF?

Thank you for any help.
