FIX PHP Fatal Error on an invalid Blip Field.

Browse Source 
For (still) unknown reasons, PHPExcel detects a wrong field type.
If there is no BSE Index, we will fail here and other fields are not read.
So if the BSE Index < 1, continue with the next field.
TODO: Why is there no BSE Index?
      Is this a new Office Version?
      Password protected field?
      More likely : a uncompatible picture
