[Mailman-Users] Simple notification handler

Hi Mark,

It seems the handler stops the list from working.  When I delete the new 
pipeline the list works fine so it's the Python file (or the way I 
included it in the pipeline ?) that has a problem.

I've tried including a she-bang line or not (see below for both the 
handler and the text file used to shove it in the list pipeline), 
importing Message in addition to UserNotification and a few other things 
to no avail.  One thing I find odd is that the handler doesn't get a 
.pyc file upon restart.  Should I expect that or does it get created the 
first time it is invoked ?

I've copied the file over from a windows machine and I took care of 
chowning it so it has the same permissions as the other Handlers.  The 
file looks ok in vi.  What other options do I have before pdb ?
