Summary0003280: Rendering a video causes a rendering crash
DescriptionI was able to render successfully my project. Then I "Saved As" it to another project, removed picture clips from it, added another in high resolution and got error like here: 0002859. Do not know why I had not this before, however I installed LADSPA and got new error:

I am still able to render original project.

Steps to reproduce:

1. Save As project with another name
2. Remove picture clips from it.
3. Added new picture clip with high resolution
4. Render.

Reduced size of "???????? ??? ??????? 1652.png" file to 1080p - 1.6MB (original size is 3339x3290, 14MB) and changed its name to english characters without spaces - renders successfully now. So problem is in characters set or in image resolution.

Sorry for late answer,
The problem during render is in MLT.
Could you try to do the test to determine what makes it fail between resolution (unlikely) and special character (which one)?
