xmlrpc call to getPageHistory does not work from Python

XWIKI ENTERPRISE 2.2.2.27483
Javadoc of trunks/core/xwiki-xmlrpc/xwiki-xmlrpc-client/src/main/java/org/xwiki/xmlrpc shows existence of getPageHistory. But can not use it from Python.

Python code:
page = proxy.confluence1.getPage(token, 'Linuxbeheer.ProjectNagios')
print page.get('id')
history=proxy.confluence1.getPageHistory(token,page.get('id'))
print type(history),history

Error text:
