[pygame] pygame parachut/coredump on pygame image load.

[Lionel Barret De Nazaris <lionel.bdn@xxxxxxx>]

Hi all,

I am trying to join BMPs into one nice mpg and pygame do the parachute 
thing to me.

It's quite puzzling because the first image is processed, but it crashes 
just after that...

Any idea ? The images are over 4000 but I don't see how that could 
affect this code or cause this core dump...
