Vincent,

I downloaded your video.  I'm also able to play it in VLC but not in 
Totem.  'ffmpeg -i' reports the following:

===
Seems stream 0 codec frame rate differs from container frame rate: 
60000.00 (60000/1) -> 30.00 (30/1)

It looks like the video contains H.264 video and AAC audio, both of 
which should play on Ubuntu (which I presume you're using since you 
uploaded to Ubuntu One).  But maybe the frame rate error message above 
is significant, or perhaps there's something odd about the container 
format.  This is really outside the scope of Shotwell, so perhaps you 
could ask your question on one of the GStreamer mailing lists.  Cheers -
