There's a cleaner fix upstream:

http://gitorious.org/webkitgtk/stable/commit/1c3ae92649aa57aad859484c7cbbdae69c73f6cd

I don't know if it can be easily backported to 1.2.7, but the bug is resolved in the new stable release 1.4.0.

This is only a part of bug, I saw this. But there is also another problem: program saves a pointer to item of vector (a frame of GIF) and then call resize of this vector. So the memory will be reallocated and that pointer will be broken... My patch fixes this bug.
