-- Information about the crash:
Gwenview crashes when browsing to video file (.mp4). This is with auto video
playback enabled. Renderer is OpenGL on laptop with Intel and Nvidia GPUs.
AFAIK, it was using Intel at the time, but may have invoked Nvidia for the
OpenGL. This is on a fresh installation of Fedora 42 KDE spin, with beta repos
enabled, though it has happened on release versions. This is also with Third
Party Repos enabled per Fedora setup (DNF). Video started, but black screen
(audio only). Application crashed about 5 seconds into playback.
The crash can be reproduced every time.
