Hi, in that trace I don't see any Kdenlive code. It's only mentioning `libprotobuf` and `libopencv_dnn`.
Looks like a packaging problem. I assume you are not using the official packages (Flatpak or AppImage)? If that is the case, try if you can reproduce the issue with the Flatpak or AppImage packages.

The issue doesn't exist in AppImage and Flatpak versions.

Comment 3 balooii 2025-06-08 18:36:02 UTC
Okay, then let me try to move this bug to neon instead of kdenlive
Comment 4 balooii 2025-06-08 18:38:40 UTC
Okay, then let me try to move this ticket from kdenlive to neon :fingers crossed:.
Comment 5 edfardos 2025-06-16 22:27:08 UTC
I'm seeing exactly the same crash here. -- confirmed.
Comment 6 Carlos De Maine 2025-08-20 23:07:43 UTC
backported and rebuilt frei0r-plugins against neon's new libopencv and kdenlive is now working as expected
