Qt Version: 5.15.2
Frameworks Version: 5.90.0
Operating System: Linux 5.14.21-150400.24.49-default x86_64

DrKonqi: 5.24.4 [KCrashBackend]

-- Information about the crash:
- What I was doing when the application crashed:
I attempted to switch projects from one that I currently had open (dubbed "Project A") to another one (dubbed "Project B"). There was only one opened instance of Kdenlive. It appeared as if Project B loaded successfully (the loading bar filled to 100% and the small loading sub-window disappeared, the clips and the timeline assembled etc), but about 1-2 seconds after this Kdenlive crashed.

I did the same thing twice again (first Project A, then Project B) and Kdenlive crashed in both instances. I tried the inverse, first switching to Project B (from an empty instance) and then switching to Project A, this worked fine and Kdenlive did not crash. I then proceeded to switching to Project B again, at which point Kdenlive crashed just as it had before. This last step (B->A->B) I repeated, with the same result.

Whenever I write "switch" what I mean is going to "File" -> "Recent Projects" and then selecting the project in question.

The crash can be reproduced every time.

-- Backtrace:
Application: Kdenlive (kdenlive), signal: Segmentation fault
