[BlueOnyx:21731] Broken mailman since last yum

[Chris Gebhardt - VIRTBIZ Internet]

Not sure that there is anything particularly related to Mailman in the 
most recent updates, but since Saturday we have a site that is unable to 
use their Mailman install.  Upon logging in to administer a list, the 
following output goes to browser:
Bug in Mailman version 2.1.15

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 Mailman error log (snipped below) seems to reference a permissions 
issue.   Changing the directory permissions on /var/lock/mailman to 777 
alleviates the error, but that seems like it could be a bit of a 
security issue.

Thoughts?
