Is this crash caused by QtAV ?

Thanks,

Yes it is, while video thumbnail is created before to be show in icon view.

This mp4 file can be played properly in digiKam video preview ?

If no, I recommend to create a new report in QtAV github project and to provide the MP4 file for investigations.

If yes, the problem is located in DK, so the report must be created in KDE bugzilla, as usual.
