Strange question in AnimatedImage

[CloudCastle]

Hello everybody,
I use many GIF by AnimatedImage in my app, they are all working with normal.
but when I load "Dave.gif"(yes, the big Dave in Plant Vs Zombie, The file size is more than 100 K)，crash happen, with no error reporting.
I mean, Is there any requirements for the GIF files loaded to AnimatedImage? such as size or some other things? Or other possible reasons for the occurrence of crash？

Thanks in advance!

Well, if I destroyed the AnimatedImage objects in the first QML before the second QML be loaded, it works. But i don't know why, AnimatedImage object can't exist two or more in the same time?
