Mailmain html page editting problem

[Marty]

I am experiancing a problem of not being able to update the General
List Information Page through the mailman interface. I can pull up the html
for the page, but when I click submit changes, I get:

Bug in Mailman version 2.1.9.cp2 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.

Any suggestions as to how to resolve this? The server is on:

WHM 10.8.0 cPanel 10.9.0-R10737
CentOS 4.5 i686 - WHM X v3.1.0

Does anybody have any ideas at all. This one is bugging me.
