Using totem-video-thumbnailer ported to GStreamer 1.0. I get:
TotemVideoThumbnailer-Message: Initialised libraries, about to create video
widget
TotemVideoThumbnailer-Message: setting URI file:///home/hadess/example.y4m
TotemVideoThumbnailer-Message: Video widget created
TotemVideoThumbnailer-Message: About to open video file

But in the debug I can see:
0:00:00.439854033 ^[[334m13671^[[00m 0x1794990 ^[[37mDEBUG ^[[00m

/GstPlayBin:play/GstURIDecodeBin:uridecodebin0/GstDecodeBin:decodebin0:\012No\

Which is a much better error message. How come that more helpful message isn't
getting posted to the bus?
This is the debug print code:

The changes for GStreamer 1.0 are minimal, see patch in bug 674078
