Description of problem:

creating vm from py-sdk fails with message:

Traceback (most recent call last):
  File "<input>", line 1, in <module>
  File "/usr/lib/python2.6/site-packages/ovirtsdk/infrastructure/brokers.py", line 22895, in add
    body=ParseHelper.toXml(vm),
  File "/usr/lib/python2.6/site-packages/ovirtsdk/utils/parsehelper.py", line 74, in toXml
    entity.export(output, 0, name_=ParseHelper.getXmlTypeInstance(type_name))
  File "/usr/lib/python2.6/site-packages/ovirtsdk/xml/params.py", line 20933, in export
    self.exportChildren(outfile, level + 1, namespace_, name_, pretty_print=pretty_print)
  File "/usr/lib/python2.6/site-packages/ovirtsdk/xml/params.py", line 20979, in exportChildren
    self.template.export(outfile, level, namespace_, name_='template', pretty_print=pretty_print)
TypeError: export() takes at most 3 non-keyword arguments (4 given)

this affects all my py-scripts and, of-course ,art.

code executed:

>>> param=params.VM(name='class_is_broken',cluster=api.clusters.list()[0],template=api.templates.get(name='Blank'))
>>> api.vms.add(param)
Traceback (most recent call last):
  File "<input>", line 1, in <module>
  File "/usr/lib/python2.6/site-packages/ovirtsdk/infrastructure/brokers.py", line 22895, in add ...

when trying to execute instead:

>>> tmp=params.Template(name='Blank')
>>> param=params.VM(name='class_is_broken',cluster=api.clusters.list()[0],template=tmp)
>>> api.vms.add(param)
