Piechaser -- The source is 'credible' enough but the report is wrong. Here is the Airbus text, from our link:
Lemain, The Airbus report is not wrong. Airbus were on the scene working alongside the AAIB!
Airbus know very well how much fuel was in each tank at point of impact.
There is a report coming out very shortly, so let's just hope everything will become much clearer and a design change will be made.
