It looks like this error comes from the fact that "eval('')" raises this.
Apparently an empty string is not valid python for the parser. It is a
little strange that an empty string is getting parsed to test for
membership in CC. Many non-empty strings that are invalid python code do
return "False", so it looks like the empty string ends up in a wrong code
path somewhere. Worth a bug report, I'd say.
