Upgrade (to 0.9.2) fails with _p_jar

Dear list members

I'm testing our upgrade procedure, which integrates all steps from Silva
0.9.1 to 1.0, with different sites.
The upgrade of a big site fails in the first step (to Silva 0.9.2) with the
following error:
AttributeError: _p_jar

The relevant stack trace is:
  File "/opt/ZOPE/ZOPESITES/UPGRADE/TEST_IDSITES/Products/Silva/upgrade.py",
line 305, in upgrade_using_registry
    if obj._p_jar is not None:

The object the failure happens is:
.../silva_ethz/ETH/id_sites/wcms/wcms/people/olafa/index/0/child%2C0%2C9
That seems to be a node in the version 0, i.e. a ParsedXML object.

Any ideas?

Regards,
Benno
