It is the same crash as in bug 376810.
I've noticed that kdenlive crashes when playing overlay effects like fade or dissolve when using GPU accelerated effects. I'm running NVidia proprietary drivers on a Quadro 4000. I've deactivated GPU acceleration and no more crushes when running only on CPU power. Hope this helps.
