      I've noticed this happening after doing deletes. When I've seen this issue before an optimize has made the issue go away. I believe this may also be related to the describe here:
      http://stackoverflow.com/questions/10124055/solr-faceted-search-throws-nullpointerexception-with-http-500-status

      I have been unable to reproduce this in a test but this has come up at least 3 times in our environments.
