[Mailman-Developers] TypeError: cannot concatenate 'str' and 'NoneType' object

[Ron Jarrell]

Well, it came back... I was poking around because I was having cron 
problems, and some jobs weren't running.. There's nothing in error, but
if you run disabled by hand, you get:


/usr/local/bin/python -S /home/mailman/cron/disabled
Traceback (most recent call last):
  File "/home/mailman/cron/disabled", line 220, in ?
    main()
  File "/home/mailman/cron/disabled", line 204, in main
    mlist.sendNextNotification(member)
  File "/home/mailman/Mailman/Bouncer.py", line 270, in sendNextNotification
    msg['Subject'] = 'confirm ' + info.cookie
/usr/local/bin/python -S /home/mailman/cron/disabled

It worked fine for a while.
