Hi ,
The very similar exception occurs while indexing a
page which do not have body content (and title
sometimes).
051223 194717 Optimizing index.
java.lang.NullPointerException
at
org.apache.nutch.indexer.basic.BasicIndexingFilter.filter(BasicIndexingFilter.java:75)
at
org.apache.nutch.indexer.IndexingFilters.filter(IndexingFilters.java:63)

org.apache.nutch.crawl.Indexer.reduce(Indexer.java:217)

org.apache.nutch.mapred.ReduceTask.run(ReduceTask.java:260)

Looking into the source code of BasicIndexingFilter.
it is trying to
doc.add(Field.UnStored("content", parse.getText()));
I guess adding check for null on parse object
if(parse!=null) should solve the problem.
Can confirm when tested locally.
Thanks
