https://github.com/void-linux/void-packages/issues/46962

Description:
### Is this a new report?

Yes

### System Info

Void 6.5.8_1 x86_64 AuthenticAMD uptodate rFFF

### Package(s) Affected

kdenlive-23.08.2_1

### Does a report exist for this bug with the project's home (upstream) and/or another distro?

https://discuss.kde.org/t/touching-any-video-file-in-my-project-bin-immediately-crashes-kdenlive-23-04/1191/6

The AppImage of kdenlive works fine, and I assume this is the case for the Flatpak or PPA of it as well.

### Expected behaviour

Normally, when clicking in kdenlive's project bin to preview a clip, you can then drag it to add to the project that you currently have open.

### Actual behaviour

Kdenlive will crash if you click anywhere in the project bin, and is (usually) not avoidable.

Output of `gbd kdenlive` is vague, but is thankfully only a few lines:

```

### Steps to reproduce

1. Install the current version of kdenlive in the void repository with `xbps-install -S kdenlive`
2. Add clips to the project bin, and try editing in the application for a bit.
3. Eventually, you will reach a point where kdenlive crashes almost every time when you click on a clip that is in the project bin.

Comment:
Both crashes are happening in `ffmpeg`/`mlt` and not kdenlive. I'm not able to reproduce this with any of the video files I have on hand.
Do you have a file that reliably crashes on your system that you can provide?

Is it reproduce-able in 23.08.4?
