I saw this myself a while ago, and I'm sure I looked into it, and for
some reason concluded that it wasn't my problem. But I've no idea how
I came to that decision :-)

It's a SWIG thing, I think - simplesearch.py uses the %extend
constructor to Query, which (once again) has ceased to work. This is
really, really unstable, and seems to rely on particular versions of
SWIG to get it right - I suspect they've tinkered something in stl.i
which has caused it to fail to recognise the parameters to the
%extend.

I'm building up SVN head at the moment (chug, chug), so I'll report
back if I find anything new. Doubt I'll have a chance to prod SWIG
that much today, and in any case I'm a little confused now as to
exactly which version of SWIG gets used for which language... I seem
to be using 1.3.26, however, which probably means I'm building from
CVS as it doesn't look like that's been released yet.
