Comment 1 Christoph Feck 2017-02-22 23:31:29 UTC

It is the same crash as in bug 376810.

Comment 2 Florin 2017-02-23 08:10:57 UTC

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.
