simple version of tuenti.com

In this website there is a bounceInUp which causes a crash with using QT-Directfb implementation.
Indeed this animation is composed of one image and a text indent of 9999em. 
A surface is created in TextureMapperLayer::updateBackingStore with a big size such as 160000x300 which is not supported by directfb, causing a crash after imageBuffer = ImageBuffer::create(dirtyRect.size());
If i remove the text indentation, this is not crashing anymore and the animation is working fine.
In attachment a simplified version of www.tuenti.com
This website is perfectly working with Chromium or Safari.
