After a lot of digging, it appears that objects in python extension
classes are never instances, so I think that code must have been written
to try to get the "vector<Query>" version working, but it has never
actually worked.

So I simply rewrote the function in question, and now this one works
too!

I'll check this in shortly, then maybe have a quick play to see if it's
easy to support a mixture of strings and Query objects.

Answering myself (after I discovered some documentation in comments in
python header files) a sequence is an abstraction which could be a list,
tuple, or other similar type (like an ordered container in C++).  So
I've moved both wrappers to use the sequence interface.
