sorting by termfreq on trunk doesn't work?

I am trying to use sorting by the termfreq function using the trunk code
since termfreq was added in the 4.0 code base.
I run this query:
http://127.0.0.1:8983/solr/select/?q=librarian&sort=termfreq(all_lists_text,librarian)%20desc

but I get:

HTTP ERROR 500

Problem accessing /solr/select/. Reason:

    null

Thanks for the problem report.  It turns out we didn't check for a
null pointer when there were no terms in a field for a segment.
I've just committed a fix to trunk.
