New submission from Nick Craig-Wood <n...@craig-wood.com>:

sqlite3.Warning isnt a subclass of exceptions.Warning

This causes this problem when trying to filter warnings

>>> import sqlite3 as DB
>>> from warnings import filterwarnings
>>> filterwarnings("always", category=DB.Warning)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python2.6/warnings.py", line 56, in filterwarnings
    assert issubclass(category, Warning), "category must be a Warning subclass"
AssertionError: category must be a Warning subclass
>>> 

Other databases do this correctly, eg

>>> import MySQLdb as DB
>>> from warnings import filterwarnings
>>> filterwarnings("always", category=DB.Warning)
>>>
