On reflection, can't we fix this as follows: if the value coming in from
Python is a string, just feed it to record_in, the same as we used to.
When I traced through the logic before, it seemed like it was failing
to distinguish strings from sequences, but I would hope that Python
is more strongly typed than that.
I still think the conversion in the other direction ought to yield a
dict, but that's clearly not back-patch material.
