Description

From http://github.com/cloudkick/libcloud/issues#issue/13:

Errors in the system can turn into XML serialization errors. The one I'm encountering now (which I haven't quite tracked down) is a name attribute with a value of None. ET constructs the nodes fine, but when you call ET.tostring() it gives a nasty exception, like:

...
File "/usr/lib/python2.5/xml/etree/ElementTree.py", line 777, in _raise_serialization_error
"cannot serialize %r (type %s)" % (text, type(text)._name_)
TypeError: cannot serialize None (type NoneType)

That's not very helpful. Guarding ET.tostring with some debugging code for exceptions would be handy.
