qrunner in loop, keeps eating memory

[Pandora]

mailman-2.0.13
python-2.2.1

Every now and then qrunner goes nuts and starts eating
up all available memory on the system. I'm attaching a
.msg and .db file which seems to reproduce the problem
at all times, and also a log trace which showed up in
the error log when I pressed CTRL-C. This last log
shows where qrunner was looping, and it's in
pickle.loads (log below).

Oct 30 16:06:47 2002 (25698) CORRUPT ARCHIVE FOR LIST:
commits

I don't know if the CORRUPT ARCHIVE message is due to
me pressing CTRL-C or if there is actually something
wrong with it.

Any help would be greatly appreciated. Thanks.
