Application: kdenlive (18.04.1)

Frameworks Version: 5.44.0
Operating System: Linux 4.15.0-29201807270420-generic x86_64
Distribution: Ubuntu 18.04.1 LTS

-- Information about the crash:
I had added the curves filter to a selected clip. When I tried to move the top right point, either left or down, Kdenlive instantly crashed.

I tried it twice, with the same result.

The crash can be reproduced every time.
