If you can include a stack trace of that error with SOAPpy, that would be 
excellent.  This sounds bizarre.

You won't be able to do anything with the ints: some of them are 
internally interned by the runtime, and you can't control this.  So I'd 
instead focus on why SOAPpy is failing.  It shouldn't have to worry about 
recursively traversing the ints: they don't have any structure to 
traverse!  So a stack trace would be useful.
