[Mailman-Users] Problem when creating new lists

[David Renstrom]

Hi,

Everytime I create a new list using the Web interface in Mailman I get the
following error:

Bug in Mailman version 2.1.14
We're sorry, we hit a bug!
Please inform the webmaster for this site of this problem. Printing of
traceback and other system information has been explicitly inhibited, but
the webmaster can find this information in the Mailman error logs. 

The file /etc/mailman/Virtual-mailman has changed ownership from mailman to
apache. I have to change it manually and then run the genaliases and postmap
commands to make the system work correctly again.

Could someone please tell me what's wrong because I'm kinda lost? See below
for more info.
