Crash on start ever since I updated

Readek · August 13, 2026, 6:04pm

I use Arch ~~btw~~, and ever since I updated my system, I’m unable to get past project select screen, as it crashes after selecting one (or even a creating a new project).

I’m not sure how to ask for help with this, so I’m gonna paste what the terminal throws to me:

If there’s anything I can do to help debug the issue please let me know!

Hi @Readek, and welcome to the forum and community.

How did you install Kdenlive? Did you use Arch’s package manager? If so, please use the AppImage or Flatpak version of Kdenlive.

Readek · August 13, 2026, 7:57pm

Huh. The AppImage works with no issues! Yes, I was using it from Arch’s repos.

This technically didn’t fix the issue, but it is a solution nonetheless.

berndmj · August 13, 2026, 8:28pm

You have to report this to the Arch maintainers. The Kdenlive team only provides and supports the AppImage and Flatpak versions. The distro maintainers do their own packaging, and while most do a proper job some distro packages are faulty. There is nothing we can do. Sorry!
