Comment 1 Giacomo Carnevale 2014-03-04 17:03:43 UTC 
Proposed fix:

In the file extensions/SemanticMediaWiki/includes/sparql/SMW_SparqlResultParser.php (line 115, method xmlHandleOpen) the property m_xml_datatype is set to false when the xml datatype attribute is not present in attributes array; but the SMWExpLiteral  __construct (extensions/SemanticMediaWiki/includes/export/SMW_Exp_Element.php file) throw new InvalidArgumentException (line 253) if the datatype param is not a string.

We fixed this replacing at line 115 of the extensions/SemanticMediaWiki/includes/sparql/SMW_SparqlResultParser.php file: 

     $this->m_xml_datatype = false;

with

     $this->m_xml_datatype = '';
