Hi,
I had the same problem and fixed it by deriving MonitoredList from list, not
UserList. Additionally, I added some __hash__ methods.
All *seems* to work (did only test a few examples) and should also work with
python 2.5.
I've attached your patch to this email for posterity.
I'll try to find some time to make it work with python 2.3 and up and
check it in.
