Key Error when ARES returned server fault instead of valid response

We encountered an Key error when ARES return Fault element instead of element Odpoved in code

Line 61 in 32f1935

response_root = ares_data['are:Ares_odpovedi']['are:Odpoved']

Based on XSD schema, it is possible ( http://wwwinfo.mfcr.cz/ares/xml_doc/schemas/ares/ares_answer_basic/v_1.0.3/ares_answer_basic_v_1.0.3.xsd ).
