Description Ovidiu-Florin BOGDAN 2017-03-13 20:28:44 UTC 
Application: kdenlive (16.12.2)

Qt Version: 5.6.1
Frameworks Version: 5.28.0
Operating System: Linux 4.8.0-41-generic x86_64
Distribution: Ubuntu 16.10

-- Information about the crash:
- Happens every time.
- What I was doing when the application crashed:

I wanted to replicate the Project Bin from one project in my new project. I opened 2 instances of kdenlive: Old project and new project.

I selected the folders I wanted from the old project's Project Bin, and dragged & dropped them in the new project's Project bin. 

Expected Results:
Folder structure to be replicated in new project, with containing files.

Actual results:
Kdenlive with the new project crashed.

-- Backtrace:
Application: Kdenlive (kdenlive), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".

Please try with the current Kdenlive AppImage version 19.08.0a to see if there are any packaging issues https://files.kde.org/kdenlive/release/ 

If the problem/issue doesn't occur when using the AppImage, then it's your configuration or packaging.

I've tested with 19.08.1 AppImage. I've opened 2 instances. Created a folder in one instance and added a video file to it. Dragging and dropping the folder the other instance gives a message that "No valid clip to insert".

Kdenlive does not crash anymore. Issue seems fixed.
