*** Bug 509504 has been marked as a duplicate of this bug. ***

After little investigation, this seems to be a Qt issue. The gwenview crashes in VideoViewAdapter class constructor when trying to create QMediaPlayer instance (videoviewadapter.cpp, line 202). I created new hello world Qt app that only tries to create media player, but upon trying to construct QMediaPlayer instance I encounter exactly same crash.

In this case, please submit the bug to the Qt Bug Tracker.

https://bugreports.qt.io/issues/

Just to clarify I have done little bit more research. To sum up: my original report (https://bugs.kde.org/show_bug.cgi?id=509504) was caused by reasons described in (https://bugs.kde.org/show_bug.cgi?id=481977) and were solved by removing obsolete libva-vdpau-driver mentioned there. As the gwenview crashed on opening the video not clicking the play button it was not duplicate of this bug.

Now the gwenview crashes when the play button is clicked (as mentioned by original reporter here). Not sure if it is caused by the qt/nvidia drivers or the way gwenview uses QGraphicsScene, but I get following stacktrace now, if I have time, I will try to reproduce it in more isolated environment.
