As you can see above, the error occurs:

Skipping XML Document "/opt/ros/indigo/share/camera1394stereo/camera1394stereo_nodelet.xml" which had no Root Element.  This likely means  the XML is malformed or missing.

I cd to the directory and found no such file, so I downloaded the file from github and put it there.
