List Collections API output as CSV causes NullPointerException

I'm trying to get a simple text listing of my collections (so that I can do some shell scripting loops [for example calling SOLR Cloud Backup on each]).  I'm getting an exception when I simply append the "&wt=csv" to the end of the collection's LIST api (eg:  http://localhost:8983/solr/admin/collections?action=LIST&wt=csv  ).  Does anyone know if this is a known bug?

<p>Problem accessing /solr/admin/collections. Reason:
<pre>    {trace=java.lang.NullPointerException
               at org.apache.solr.response.TabularResponseWriter.getFields(TabularResponseWriter.java:71)

Thanks.
