#14 FSDirectory ReadInternal error

[JOD]

Hi,
I am getting an ObjectReference not set to instance of an
object. Please see stack trace below. I'm not doing anything
too strange, i just get values from a database create an
index (which has the right number of hits, sometimes the hit
documents are empty but that's another propblem). I then
use
Query mfQuery = MultiFieldQueryParser.Parse
(m_queryString, m_fields, new StandardAnalyzer());
to run my search.

This is kind of urgent on my end so any help would be
appreciated. I am using dotLucene 1.4.3 build 002
