Hi,
on my project, when I click "Render" or press CTRL+Enter Kdenlive just quits with this message:

Code: Select all

Cannot creat accessible child interface for object:  QTreeWidget(0x5902400, name = "scripts_list")  index:  0
Segmentation fault (core dumped)

It looks like something to do with Qt? Still, I tried saving the project to another file and removing any clips or other content and trying to render still fails this way. A new, as empty project will bring up the render dialog however.
Any suggestions what I can do?
I am using Kdenlive 16.04.1, Melt 6.1.0, ffmpeg 2.8.6-1ubuntu2 with Ubuntu Studio 16.04.

Something wrong with scripts: maybe try to empty your "scripts" folder?

If you mean the scripts folder in the KdenLiveProjects folder: I emptied it, no change, still crashing. I am not saving my project file in this folder, so I renamed the KdenLiveProjects folder and let KdenLive create a new one. Still crashing.

Also reproducable: After opening and closing the render dialog on the new, empty project on startup of KdenLive, trying to load the "faulty" project file will crash too, with no log in the terminal, just Segmentation Fault.

Everything works when trying the project on a different computer. Something with Ubuntu Studio, my setup or my configuration must be off. I guess I will try to take the project to a different computer or re-install Ubuntu Studio.

Thank you for the suggestion anyway.

You could try to search for sunab ppa and install all components from there.
Check this: https://launchpad.net/~sunab/+archive/u ... ve-release

I don't know if that would help, since I can't import a 16.04 project into KdenLive 15.12.
I would have to spend days to re-create my project to test, and that is what I am trying to avoid.

But thank you for the reply. I will use this PPA on my new Ubuntu Studio install.

I have found that the render settings saved in the .kdenlive project file cause KdenLive to crash when trying to open the render dialog.
By deleting the following properties, KdenLive wouldn't crash anymore:

I hope this helps the developers to figure out what happened and how to fix it in a future release.
