 Dave,

 The use of 'super' with __init__ does in fact work, as long as all classes
 use it:
 {{{
 class A(object):
     def __init__(self):
         super(A, self).__init__()
         print 'A'

 class B(object):
     def __init__(self):
         super(B, self).__init__()
         print 'B'

 class C(A, B):
     def __init__(self):
         super(C, self).__init__()
         print 'C'

 c = C() # prints A B C
 }}}

 The reason for this is pretty well explained in http://fuhm.net/super-

 harmful/. In a nutshell: super() doesn't (necessarily) invoke the
 superclass method itself, but the next one in the MRO chain. If you omit
 super in one case, you break out of this chain.

 FWIW.
