[Mailman-Users] Mailman Error

[Srinivas B.]

Hi

Seeing the following errors in mailman log:

Dec 10 20:06:25 2013 (20635) Uncaught runner exception: Generator instance
has no __call__ method
Dec 10 20:06:25 2013 (20635) Traceback (most recent call last):

The above is after trying the patch to use "g.flatten(msg, 1)" in place of
"g(msg, 1)". But neither worked and gives pretty much the same error as
above.

Do I need to reinstall mailman or something else? How do I go about
checking any configuration or setup issues at my end?

Environment:

OS: Amazon Linux on AWS

[root at awshost postfix]# /usr/lib/mailman/bin/check_db --all --verbose
List: gclist
   /var/lib/mailman/lists/gclist/config.pck: okay

[root at awshost mailman]# /usr/lib/mailman/bin/check_perms -v

No problems found

Thank you in advance.
