Description garduino512 2023-05-04 16:16:05 UTC 
SUMMARY
Kdenlive crashes upon selecting a video clip from the project bin. This can be done through either by clicking on the video clip or by using the arrow keys to move the selection from an adjacent non-video clip. Strangely, this seems to be a permanent phenomenon as this doesn't happen with new projects or saved projects that have not crashed from this bug before. Once your project crashes once because of this bug, it will crash again from that point on when you select a video clip.

STEPS TO REPRODUCE
1.  Lauch Kdenlive
2.  Open a saved project
3.  Click or use the arrow keys to select a video clip

OBSERVED RESULT
Clip should get selected with no issues and clip monitor should become active.

EXPECTED RESULT
Kdenlive crashes due to a segmentation fault.

There have been several bug fixes done in the last days. Please try with the daily AppImage if the issue still occurs. https://binary-factory.kde.org/job/Kdenlive_Nightly_appimage-centos7/lastSuccessfulBuild/artifact/
