KeyError on membranepassword.IProvidePasswords

[mikejmets]

I upgraded a site to plone 4.3.10 and dex.membrane 1.1.1 and changed all references to IProvidePasswords in a local addon from membranepassword to password. If I create a new object that refers to a membrane actor it works fine but when I modify an existing object that refers to a membrane actor I get a key error on save. ...

• Module zc.relation.catalog, line 556, in unindex_doc
• Module zc.relation.catalog, line 621, in _remove KeyError: <class 'dexterity.membrane.behavior.membranepassword.IProvidePasswords'>

I don't see any upgrade steps in d.membrane. I did rebuild the catalog and tried a few other trick to no avail. Is there an upgrade step that I'm missing? As a workaround, I created a fork with an import of IProvidesPasswords from password in membranepassword.
