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.
