Comment:
Well, this is the traceback I get whether the QuerySet is empty or not:
{{{

}}}
but now that I think of it, we probably don't want this error to fail
silently since it's an unsupported feature with QuerySets, and is not
really the fault of the filter.
My error doesn't appear to be the same one you are seeing. If you could,
please post more information. The full traceback, the query you are
assigning to `films`, and the generated SQL would be great. Without that,
closing this ticket as invalid as I am unable to reproduce the error you
are seeing.
