Project with the issue
SUMMARY
When the timeline has text (dynamic text, title clip) the rendering fails
(presumably) with
QGuiApplication::font(): no QGuiApplication instance and no application font
set.
STEPS TO REPRODUCE
1. Create a title clip with some text
2. Add the title clip to the timeline
3. Make a preview render including the title clip
OBSERVED RESULT
Preview render fails when it gets to a part with the text
EXPECTED RESULT
Preview render succeeds
SOFTWARE/OS VERSIONS
Linux: 6.4.3-arch1-2
KDE Frameworks Version: 5.108.0
Qt Version: 5.15.10
MLT Version: 7.16.0-2
ADDITIONAL INFORMATION
This issue doesn't happen when making a full render.
I think the issue is upstream in MLT but I'm not certain.
I'm not sure about the error message because "Show details" button works only
sometimes for me.
It could be an issue on my end due to possibly incorrect installation of fonts,
but i didn't find any useful information online.
I have attached a minimal project that reproduces the issue.
