Victor, Making that change doesn't appear to change anything when invoking -D.

I remember somebody saying that MD5's were not logged with -D mode, as
such I tested it and it works without -D. My apologies for posting to
the mailing list, Should have checked redmine first.

For anyone that is interested, the redmine link is:
https://redmine.openinfosecfoundation.org/issues/449

Thanks for the fast response Victor, keep up the great work.
