Looks like this is the reason - the get_dialect call (which is
implemented in C) is now returning a read only Dialect object rather
than an instance of the original class :-
2.5
>>> import csv
>>> d = csv.get_dialect('excel')
>>> d.__class__
<type '_csv.Dialect'>
>>>
2.4
>>> import csv
>>> d = csv.get_dialect('excel')
>>> d.__class__
<class csv.excel at 0xb7d1f74c>

Don't you want to do this anyway?
import csv
class my_dialect(csv.excel):
delimeter = ","
