[Python-Dev] threading bug? (original) (raw)

[Apologies, I also asked this on c.l.p, but got no answer so far. I have not too much time left before I will be away for nearly 2 weeks]

I wonder if this is a bug. I'm running a deamon thread doing some work in the background, and sometimes when Python exits I get tracebacks like this:

Unhandled exception in thread: Traceback (most recent call last): File "c:\python21\lib\threading.py", line 393, in __bootstrap self.__stop() File "c:\python21\lib\threading.py", line 399, in __stop self.__block.notifyAll() File "c:\python21\lib\threading.py", line 235, in notifyAll self.notify(len(self.__waiters)) File "c:\python21\lib\threading.py", line 217, in notify me = currentThread() TypeError: object of type 'None' is not callable

This traceback does not appear when I register an atexit function to stop the thread.

Is this a bug? Aren't daemon threads supposed to clean up themselves?
