Jorge Godoy reported a similar error a few days ago, but it didn't
turn out to be a problem with the filter. He mentioned the
AutoCompleteWidget, but I'm not completely clear on what the root
cause of the problem was.
The decoding filter runs *before* our decorators and, in theory,
before the NestedVariablesFilter. That means that the decoding filter
shouldn't be getting a dict from us.

I'm not sure that this is a CherryPy bug. The decoding filter pretty
reasonably expects strings to be coming in. I'm just not certain how
you're getting this error given the order of processing (CP's input
filters come before ours, so DecodingFilter should come before
NestedVariablesFilter.)
