This is almost certainly something strange with the XML parser you are 
using. Have you installed a particular version of PyXML? Or are you 
just using Python bare?

ark tries to do The Right Thing with whatever XML parser you have 
available, but it looks like the one it's chosen is broken. Can you try 
the following things in Python and let us know what you get:

 >>> import xml
 >>> xml.__version__
'1.13'

 >>> import xml.dom.minidom
 >>> doc = xml.dom.minidom.parseString( '<test><me/></test>' )
 >>> root = doc.documentElement
 >>> len( root.attributes )
0

It's probably just another special case that we need to add to the 
parser detection logic.
