AttributeError with PAM on Plone 4.3.20

Hi Plone,

I want to use plone.app.multilingual on Plone 4.3.20. I installed PAM version 2.x from GitHub. PAM seems to work fine, but it prevents deleting the Plone site from the Zope instance. When I attempt to delete the Plone site with PAM in the buildout, I encounter the following issue:

Error Type: AttributeError
Error Value: 'NoneType' object has no attribute 'unrestrictedSearchResults'

This is the traceback:

  Module plone.app.multilingual.manager, line 95, in update
 AttributeError: 'NoneType' object has no attribute 'unrestrictedSearchResults'

Can I leave it this way and accept the fact that the Plone site cannot be deleted from the instance, or is this something that needs to be fixed before continuing? If it needs a fix, how?

Thank you in advance

This looks like a multilingual bug:
As you wrote, you try to delete a site but the
archetypes_creation_handler is activated and it apparently
expects to see a functional catalog but sees None instead
(the latter is likely the result of a previous event handler).
It is strange that a creation handler is called for a deletion.

Potentially, you can work around the bug by first
uninstalling multilingual in the site and only then delete this site.

Thank you for your response but this workaround does solve the issue. The error occurs already when PAM is in the buildout and not yet installed in the Plone site. Without archetypes.multilingual the issue is not there.
