It looks like playbin2 is not working on your device.  This can be 
easily verified without using Rygel.

From the command line simply type

gst-launch-0.10 playbin2 uri=file:///home/me/myvideo.wmv

where ///home/me/myvideo.wmv is the path to a video file stored locally 
on your device?  If this doesn't work it implies that playbin2 is not 
working properly on your device.

BTW., are you planning to use Rygel as a DMR or a DMS or both?  If you 
only want to use the DMS functionality you can probably get Rygel to 
start on your device by disabling the playbin plugin in the rygel.conf file.

In any case, I guess we should see if we can detect the case when 
playbin is not working and simply disable the playbin plugin rather than 
asserting.
