[Mailman-Users] TypeError: cannot concatenate 'str' and 'NoneType' objects

[Bernd Petrovitsch]

Hi!

I get the following on mailman-2.1.5 on Debian-Sarge:
> Traceback (most recent call last):
>   File "/usr/lib/mailman/cron/disabled", line 222, in ?
>     main()
>   File "/usr/lib/mailman/cron/disabled", line 205, in main
>     mlist.sendNextNotification(member)
>   File "/var/lib/mailman/Mailman/Bouncer.py", line 261, in sendNextNotification
>     msg['Subject'] = 'confirm ' + info.cookie
> TypeError: cannot concatenate 'str' and 'NoneType' objects

I found http://mail.python.org/pipermail/mailman-developers/2005-July/018161.html
and did what is described there and it doesn't help anything.
Any other idea?

	Bernd
