NullPointerException encountered when /select query on solr.TextField.

I have two fields, one is title and the other is description in my Solr schema like -
Type - <fieldType name="text" class="solr.TextField" positionIncrementGap="100"/>

Declaration - <field name="description" type="text" indexed="true" stored="true"/>
without any tokenizer or filter.

On querying /select?q=description:myText it works. However when I add a '*' it fails.

Failure scenario -
/select?q=description:*
/select?q=description:myText*
.. etc

solrconfig.xml -

<requestHandler name="/select" class="solr.SearchHandler">
<lst name="defaults">
<str name="echoParams">explicit</str>
<int name="rows">10</int>
<str name="df">title</str>
</lst>
</requestHandler>
