I've also got a segmentation fault once when I was loading that page, this is why I'm putting this as high priority bug. Valgrind points out a lot of calls to TextureMapperLayer::syncAnimations() but I'm not sure if this is relevant yet.

I've just got the seg fault again, and it seems that the error was on LayerBackingStoreTile::setBackBuffer. As this itself doesn't seem to do any harm, the function that called it, LayerBackingStore::updateTile, has an assert there. I assume the problem was there (I was on release mode).
