[Mailman-Users] qrunner troubles after install: "Uncaught runner exception"

[A.N.Varady]

Hello,

Just upgraded from 2.0.13 for all the new features and have run into a
dead end. I installed mailman with the following configure:

./configure --with-cgi-gid=99 --with-mail-gid=mailman
--prefix=/home/mailman --with-python=/usr/local/bin/python2.2

and my MTA is postfix. I followed the instructions in the README,
INSTALL, and README.POSTFIX files. When I send a test message to my list
I see this error:

=============================================

This error was in logs/error: "Jan 15 23:47:21 2003 qrunner(14283): "


Any ideas anyone on how I can fix this, or otherwise rollback to 2.0.13?
Thanks!
