[Zope] 2.13 upgrade problems

[Peter Bengtsson]

I'm getting the error below when trying to boot up a zope 2.13.7 using
a Data.fs I took from a zope 2.8.12 instance.
Having Products.ZSQLMethods-2.13.3 installed or not installed doesn't
appear to be relevant.
The fortunate thing, in this instance, is that the SQLMethods in that
instance are not important to me so I'd be happy to delete them if I
could.
However, I tried with ./bin/zopectl debug
>>> del app.www['id_of_a_zsql_method']
but that raises the same TypeError.

Any ideas?
