New submission from INADA Naoki <songofacandy at gmail.com>:

When exception raised in logging, traceback is shown but it doesn't tell
me which logging code cause the error.

$ cat unusable_traceback.py 
import logging
logging.warn('%s %s', 1) # not enough arguments.

$ python unusable_traceback.py 
Traceback (most recent call last):
  File "/usr/lib/python2.6/logging/__init__.py", line 768, in emit
    msg = self.format(record)
  File "/usr/lib/python2.6/logging/__init__.py", line 648, in format
    return fmt.format(record)
  File "/usr/lib/python2.6/logging/__init__.py", line 436, in format
    record.message = record.getMessage()
  File "/usr/lib/python2.6/logging/__init__.py", line 306, in getMessage
    msg = msg % self.args
TypeError: not enough arguments for format string
