Thanks for the (detailed :-) info.  To fix this, in cert/ext_wr.c, line 753,
change:

  if( checkAttributeProperty( attributeListPtr,
                              ATTRIBUTE_PROPERTY_BLOBATTRIBUTE ) )

to:

  if( checkAttributeProperty( currentAttributePtr,
                              ATTRIBUTE_PROPERTY_BLOBATTRIBUTE ) )

Peter.
