Created attachment 153698 [details] Backtrack from KDE's crash handler STEPS TO REPRODUCE * Started a new blank Kdenlive project * Import 3 video clips (h265 mp4) and one audio clip (wav) into the project bin * Created a new AV track (as well as the two existing AV tracks that are there by default) by right-clicking on the existing track and using the "insert track" dialog * Dragged each video clip from the project bin to a corresponding track * Tried to create a new audio track for the WAV file - but when I hit "OK" in the "insert track" dialog Kdenlive exits immediately After restarting Kdenlive and using the recover-from-crash feature, everything works perfectly. OBSERVED RESULT Kdenlive crashes EXPECTED RESULT New audio track added I've attached the file generated by KDE's crash handler with the backtrace - I tried to raise the bug through there originally but it failed.
Two things from glancing at the crash report briefly: 1. It looks like the crash was in the movit library. Can you try going into the Kdenlive settings -> Playback -> disabling "Use GPU Processing"? 2. You are using Kdenlive 20.12.3 and many things have changed since then. I would suggest using the AppImage from kdenlive.org if it does not cause problems for your current project. Sometimes the distribution packages can have bugs with dependencies.

Thanks for the quick reply! I can't reproduce this with the latest AppImage or with GPU Processing disabled so I think it would be OK to close this for now then.
