Openshot segmentation fault while editing

[Mandeep Singh]

I just started using Openshot. I found it easy to use. But it keeps crashing. Whenever I do some clipping in the timeline and then press the Play button (or space key) then it crashes. Sometimes, navigating through the timeline also make it crash.

See the details: https://gist.github.com/mandeeps708/73b … 10fae46b14
See Line no. 399 (last line). This happened when I tried playing the clip after some editing (clipping).

I searched about the crashing and found that there are other users affected (on Ubuntu etc.).
64-bit Architecture
OS: ArchBang (Arch + Openbox), 4.4.1-2-ARCH
My Openshot version 1.4.3
MLT: 0.9.8-5
ffmpeg version 2.8.6
Also installed Movit 1.3.0-1

Tell me if I need to tell anything else.

I'm getting the same error while moving back in the timeline:

in /var/log/syslog I get

BTW, openshot-qt --version:

I have the same issue.

Ubuntu 16.04.2 LTS
ffmpeg: 2.8.11-0ubuntu0.16.04.1
MLT: 6.0.-2

I've read that updating MLT will resolve the issue, but those threads are also several years old, so my version is already newer than the newest available at time the threads were made.
