Created attachment 124873 [details] backtrace STEPS TO REPRODUCE 1. start kdenlive 2. open an existing project OBSERVED RESULT segmentation fault SOFTWARE/OS VERSIONS Linux/KDE Plasma: KDE Plasma Version: 5.17.4 KDE Frameworks Version: 5.65.0 Qt Version: 5.14.0 ADDITIONAL INFORMATION The only way to successfully open a project is to pass it as command argument. kdenlive also crashes on closing the app, even when I do nothing between starting and closing it. In kdenlive 18.12 everything works fine. The crashes also occur, when I run kdenlive under a new user (just to rule out any effects of configuration, caches and so on). All this happens since about 14 days. Sorry, I don't remember all the system updates that came recently. The crash can be reproduced every time.
