daily build 20081219-404 on windows vista, jdk 1.6.0_11

I created the following 2 classes. While trying to edit the 2nd attribute in the "Child" class' constructor and the
caret is on the right of "self." after typing the dot, the NPE popped up. See attached ide log file for NPE stack trace.

class Parent():
    at1 = 1
    at2 = "What!"
    def __init__(self, val1):
        self.at1 = val1

class Child(Parent, WHATISIT):
    def __init__(self, val):
        self.at1 = val
        self.
