Summary: copy.deepcopy exceptions.TypeError: 'NoneType' object ...

Initial Comment:
when using copy.deepcopy on certain objects I get
(after a large number 
of copier/_deepcopy_something):
 
filename="/usr/lib/python2.3/copy.py" line_number="179"
function_name="deepcopy"
    y = copier(x, memo)
filename="/usr/lib/python2.3/copy.py" line_number="250"
function_name="_deepcopy_tuple"
    y.append(deepcopy(a, memo))
filename="/usr/lib/python2.3/copy.py" line_number="179"
function_name="deepcopy"
    y = copier(x, memo)
filename="/usr/lib/python2.3/copy.py" line_number="270"
function_name="_deepcopy_dict"
    y[deepcopy(key, memo)] = deepcopy(value, memo)
filename="/usr/lib/python2.3/copy.py" line_number="179"
function_name="deepcopy"
    y = copier(x, memo)
filename="/usr/lib/python2.3/copy.py" line_number="243"
function_name="_deepcopy_list"
    y.append(deepcopy(a, memo))
filename="/usr/lib/python2.3/copy.py" line_number="206"
function_name="deepcopy"
    y = _reconstruct(x, rv, 1, memo)
filename="/usr/lib/python2.3/copy.py" line_number="353"
function_name="_reconstruct"
    state = deepcopy(state, memo)
filename="/usr/lib/python2.3/copy.py" line_number="179"
function_name="deepcopy"
    y = copier(x, memo)
filename="/usr/lib/python2.3/copy.py" line_number="270"
function_name="_deepcopy_dict"
    y[deepcopy(key, memo)] = deepcopy(value, memo)
filename="/usr/lib/python2.3/copy.py" line_number="198"
function_name="deepcopy"
    rv = reductor(2)
exceptions.TypeError: 'NoneType' object is not callable

Hope this is enough traceback
