Czy mógłbyś pomóc mi rozwiązać następujący problem niezgodności między Pythonem 2.5 a 2.6?

logger.conf:

<code>[loggers]
keys=root,aLogger,bLogger

[handlers]
keys=consoleHandler

[formatters]
keys=

[logger_root]
level=NOTSET
handlers=consoleHandler

[logger_aLogger]
level=DEBUG
handlers=consoleHandler
propagate=0
qualname=a

[logger_bLogger]
level=INFO
handlers=consoleHandler
propagate=0
qualname=b

[handler_consoleHandler]
class=StreamHandler
args=(sys.stderr,)
</code>

module_one.py:

<code>import logging
import logging.config

logging.config.fileConfig('logger.conf')
a_log = logging.getLogger('a.submod')
b_log = logging.getLogger('b.submod')

def function_one():
    b_log.info("function_one() called.")
</code>

module_two.py:

<code>import logging
import logging.config

logging.config.fileConfig('logger.conf')
a_log = logging.getLogger('a.submod')
b_log = logging.getLogger('b.submod')

def function_two():
    a_log.info("function_two() called.")
</code>

logger.py:

<code>from module_one import function_one
from module_two import function_two

function_one()
function_two()
</code>

Wyjście wywołania logger.py w Ubuntu 9.04:

<code>$ python2.5 logger.py
$

$ python2.6 logger.py
function_one() called.
function_two() called.
$
</code>
