Videos can't be opened with Gwenview. When switching from image to video, the program crashes completly or the video is paused, clicking play button doesn't work, it shows less than 1 second without sound and pauses again. It happens with all formats, I haven't been able to open any videos.
Opening the video from dolphin directly always causes the pause problem, the program doesn't close.
