ximagesink not working in Debian Wheezy?

[W.A. Garrett Weaver]

I've been working with gstreamer in Debain Wheezy testing, I don't think
ximagesink is working, although the rest of gstreamer seems to work.

For example this script:
gst-launch-0.10 dv1394src num-buffers=500 ! dvdemux ! dvdec !
ffmpegcolorspace ! x264enc ! matroskamux ! filesink location=video.mkv

Creates a file just fine,

If I want to output the stream to the screen (which is a very similar
script):
gst-launch-0.10 -v dv1394src ! dvdemux ! dvdec ! ffmpegcolorspace !
ximagesink

I get:

The almost identical:
gst-launch-0.10 -v dv1394src ! dvdemux ! dvdec ! ffmpegcolorspace ! fakesink

Throws no errors.

Is this a problem with my script, or could it be a bug with Debian? Could
it have been with the way I installed GStreamer (sudo apt-get install
gstreamer0.10)?
