Description Ovidiu-Florin BOGDAN 2016-04-10 08:50:55 UTC

Adding the speed effect to some clip sections makes those sections invisible after reopening Kdenlive.

They are still there, apparently, but they are not shown in the timeline.

Reproducible: Always

Steps to Reproduce:
1. open project
2. set speed to 200 on first clip
3. move second clip
4. set speed to 200 on 3rd and 4th clip
5. save
6. close and reopen kdenlive/project 

Actual Results:  
3rd and 4th clips are not shown in the timeline. When putting the cursor where they should be, project preview shows there is video content there.

Expected Results:  
clips to be shown in the timeline.

I've made a screen capture of the event happening.
Please note that I'm using the master ppa. I'm on Kubuntu 15.10 with backports.
I'm up to date with the packages available now.

I'm attaching the video and the project files.

"Viteză" means "Speed". I forgot to switch language for the recording.
