Bug#801678: gnome-sushi: green box instead of video

[Jan Gerber]

Package: gnome-sushi
Version: 3.18.0-1
Severity: important

opening any video file, sushi shows a green box instead of the video.
The size of the preview matches that of the video, seeking works and
sound plays fine but only a green box is shown.
The videos play find in totem or gst-launch playbin url=file://.
