kdenlive 26.04.3 aborts

Hi,

I was having trouble with iPhone viewing an mp4 file rendered by:
kdenlive-25.12.1

so I checked if there was a newer version available, and there was:
kdenlive-26.04.3

so I did 'pkg upgrade' which deleted kdenlive rather than upgrade it.

I installed kdenlive again (26.04.3) but it does not work:

	::::: SHOWING WELCOME!!!!!!
	:::::::::: CREATING SPLASH SCREEN SPLASH
	QGLXContext: Failed to create dummy context
	qrc:/qt/qml/org/kde/kdenlive/Splash.qml:190:13: QML Image: Error decoding: qrc:/pics/splash-background.webp: Unsupported image format
	QRhiGles2: Failed to create temporary context

	Failed to initialize graphics backend for OpenGL.

	[2] + Abort                /homes/sjg/bin/Kdenlive 


Kdenlive is just a wrapper to set LANG and supress core files:

	#!/bin/sh

	# sadly libmlt core dumps
	ulimit -c 0
	LANG=C.UTF-8 exec kdenlive "$@"

This is all on

	FreeBSD beast.crufty.net 14.4-RELEASE-p8 FreeBSD 14.4-RELEASE-p8 releng/14.4-n273754-3de2d29b088e GENERIC amd64

using packages from url: "pkg+https://pkg.FreeBSD.org/${ABI}/quarterly"

Any suggestions?

Thanks
