Summary0003073: Crash when moving keyframe in Affine
DescriptionIn a project with a "main" video clip and many titles (titles containing PNG images with transparent background) each of them with an Affine transition with several keyframes, one at the end of the title clip, kdenlive always crashes when moving the last keyframe to the end of the a title clip after extending its length to the right, but always only after repeating this for a few times.

Looking at the backtrace, I think it is an MLT rather than a kdenlive UI issue.
Steps To Reproduce- Select a title clip and extend its length to the right by a few frames or seconds
- Select the Affine transition of the clip and move the last keyframe to the end of the clip
=> Works fine
- Repeat the above with other title clips for about two times
=> Crash

I tried to reproduce this in a simple project with a movie clip and just a few title clips and did not succeed. In my project which contains more than hundred title clips (used as subtitles) I can however consistently reproduce it.

Workaround: Delete the Affine transition and create a new one, or delete the last keyframe and add a new one at the end of the clip.
