Summary: xml.xpath.Evaluate(".//a",xml_node) fails after 0.8 -> 0.8.x

Initial Comment:
Evaluating path raises exception after upgrade from 
0.8 to 0.8.2 / 0.8.3. in really simple xpath which 
should work IMHO. 
 
Testcase included in attachment. 
 
 
 
 
Invocation with PyXML 0.8.3 / 0.8.2 :

./xpath-bugreport.py 
xml_node: <DOM Element: table at 0x81b7674>
