Dan,


Bugs fixed.

Thanks for spotting, nothing like an additional pair of eyes from the 
outside :-)

The workflow for fixing existing AMIs is as follows:

Option 1:
1. Instantiate a new AMI
2. Perform the Restore from backup

Option 2:
1. Simply upgrade the "dbpedia_dav.vad" package via the Virtuoso Conductor
