Bad xmlrpc response from CH2 SA

I can actually create a slice (yay!), but the response from the geni-sa endpoint when doing so is malformed:

<?xml version="1.0"?>
<methodResponse>
<params>
<param><value><struct>
<member><name>protogeni_error_log</name><value><string>urn:publicid:IDN+emulab.net+log+e26d3de4f80edb3ad5a5817605bec69d</string></value></member>

The SLICE_EXPIRED boolean needs to have an actual value (preferably False.. :-)), otherwise geni-lib bails out on:

...
  File "/usr/lib/python2.7/xmlrpclib.py", line 557, in feed
    self._parser.Parse(data, 0)
  File "/usr/lib/python2.7/xmlrpclib.py", line 823, in end
    return f(self, join(self._data, ""))
  File "/usr/lib/python2.7/xmlrpclib.py", line 853, in end_boolean
    raise TypeError, "bad boolean value"
TypeError: bad boolean value
