Summary: Exceptions when a thread exits

Initial Comment:
[forwarded from http://bugs.debian.org/195812]

The application mentioned is offlineimap, available
from ftp://ftp.debian.org/dists/unstable/main/source/.

This behavior is new to Python 2.3.

When my application exits, I get a lot of these messages:

Traceback (most recent call last):

I went to the FTP site and all I found was some huge, 
compressed files (after changing the path to ftp://ftp.debian.org/
debian/dists/sid/main/source); no specific program called 
offlinemap.  If it is in one of those files can you just add the file 
to the bug report?

As for the reported bug, it looks like currentThread is being 
redefined, although how that is happening is beyond me.  I 
checked the 'threading' module and no where is currentThread 
redefined which could lead to None.  Has the app being run been 
changed at all since Python 2.2 was released?
