Comment:
The problem here is being caused by Python itself. For a couple of
releases of Python 2.6, http://bugs.python.org/issue1242657 meant that
exceptions raised during iteration were transparently swallowed by the
iteration process. The field error *is* being raised; but the fact that
you're iterating over the results means that the exception is eaten,
resulting in an empty result set.
If you're on a Mac with a default Snow Leopard Python install, you have
Python 2.6.1, which is affected. If you have an up to date Python install
(2.6.5 at time of writing), the problem has been fixed. I *think* it was
fixed in Python 2.6.2, but I haven't got an install handy to check.
Since this appears to be due to a bug in Python that has been addressed,
and it's a non-trivial thing to work around, I'm going to mark this
wontfix. If you are affected by this, the solution is to upgrade to Python
2.6.5+.
