What version of ctypes are you running?  I can't test this code (win32), but I 
just downloaded ctypes current (0.9.6), and a quick grep does show that 
function in a LOT of places:

abdul[ctypes-0.9.6]> egrep -rn create_string_buffer *
ctypes/__init__.py:43:def create_string_buffer(init, size=None):
ctypes/__init__.py:44:    """create_string_buffer(aString) -> character array

character array

ctypes/decorators.py:13:...     buf = create_string_buffer(256)
docs/tutorial.stx:232:    blocks, ctypes has a 'create_string_buffer' function 
which creates these in

byte buffer, initialized to NUL bytes
docs/tutorial.stx:241:      >>> p = create_string_buffer("Hello")      #

Perhaps you could try updating ctypes, and seeing what happens.
