SUMMARY Missing package on Ubuntu causes crash. Fix is to run "sudo apt install qml-module-qtquick-shapes". However, this should be done automatically. The conclusion is that this qt module is simply missing from being listed as a dependency for kdenlive. STEPS TO REPRODUCE 1. Install Kdenlive on Ubuntu 24.10 2. Select a clip 3. Add the "Motion Tracker" effect. OBSERVED RESULT Crash. EXPECTED RESULT Not a crash.
