First, thank you for the test case.

That particular behavior is expected (but maybe not correct-- your test 
case nicely summates what is currently being debated in the rest of 
this thread).

The bridge automatically converts any instance of NSString going from 
ObjC->Python to a Python String.  End result is this...

            self.string = NSMutableString.stringWithCapacity_(20)

... causes self.string to be a Python string [likely of length 0].
