Description Evert Vorster 2016-02-14 02:43:15 UTC

I have a strong feeling that this is related to bug 359365.

I worked on a project in my virtual machine, and actually rendered out a video. I wanted to re-render the video with x265, so I decided to run it on real hardware. 
I am able to load the project into kdenlive just fine, but when I click on render it crashes. 
I am able to hit render on a completely new project, and that works fine, it's only when I render a project that was recently saved that kdenlive's UI segfaults

Reproducible: Always

Steps to Reproduce:
0. Make project with loads of deep filter stacks
1.Save project
2.re-start kdenlive
3.load project
4. Hit "render"

Actual Results:  
UI Segfaults

Expected Results:  
Rendering dialog to appear

Project file that crashes kdenlive

This is an example of a project that was saved with kdenlive.
It loads fine, but segfaults when trying to render
