Summary: qrunner segfaults on specific message

Initial Comment:
I received the following bounce message to the -admin 
account on a mailing list I run. When qrunner tries to 
process this message, it segfaults, and leaves its locks. 
When subsequent qrunner passes occur, it just 
complains that it can't get the lock. Removing the locks 
just causes it to segfault again.

The only solution I've found it to simply remove the 
message from the queue.

This originally happened with Mailman 2.0.8, but I 
upgraded to 2.0.11 and it still occurred. I was able to 
reproduce the problem by mailing the contents of the 
message to the -admin address again.

The .msg and .db files are attached.

I've no idea why you get a core dump, but by definition it
must be a bug in Python.  No Python script should ever be
able to crash the interpreter.

I can't find anything wrong with the files you uploaded.  Is
there any chance you can 1) run gdb on the resulting core
file to get a stack trace; 2) upgrade your Python to
something newer than 1.5.2?
