If I run the latter script, noting that I want only WARNING and more severe messages in the log, then test.log is perhaps as expected:

[2010-09-16 09:31] WARNING: lbprivate: Warning
[2010-09-16 09:31] ERROR: lbprivate: Error
[2010-09-16 09:31] CRITICAL: lbprivate: Critical

but I get spurious output on the console:

Keep this line with the next, no gaps wanted
[2010-09-16 09:31] DEBUG: lbprivate: Debug
[2010-09-16 09:31] INFO: lbprivate: Info
[2010-09-16 09:31] NOTICE: lbprivate: Notice
Keep this line with the previous, no gaps wanted

So to my way of thinking, the logbook default is bad. The first thing I think is, "what the heck is lbprivate"?

lbmod.py

from lbprivate import private_library_function

def library_function():
    private_library_function()

lbprivate.py

import logbook

logger = logbook.Logger(__name__)

def private_library_function():
    logger.debug('Debug')
    logger.info('Info')
    logger.notice('Notice')
    logger.warning('Warning')
    logger.error('Error')
    logger.critical('Critical')

lbtest.py

import logbook
import lbmod
import sys

logger = logbook.Logger(__name__)
handler = logbook.FileHandler('test.log', 'w', level='WARNING', bubble=False)
with handler.applicationbound():
    print >> sys.stderr, 'Keep this line with the next, no gaps wanted'
    lbmod.library_function()
    print >> sys.stderr, 'Keep this line with the previous, no gaps wanted'
