Hello,

I just upgraded to Mailman 2.1.16 and python 2.7 (I was still on MM 2.1.11 with python 2.3)

=> with a topics-enabled list, I had a few shunted files with this message :

Nov 14 11:04:29 2013 (21875) Uncaught runner exception: change_header() got an unexpected keyword argument 'Delete'

File "/var/local/mailman/Mailman/Handlers/Tagger.py", line 74, in process

mlist, msg, msgdata, Delete=False)

so I modified this:

http://bazaar.launchpad.net/~mailman-coders/mailman/2.1/view/head:/Mailman/H...

on line 74, use delete=False, instead of Delete=False
