Bug in Mailman version 2.1.26

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. 

I was trying to log in to the mailman pending admin tasks page to
delete an attempted post by a non-member. 

in /var/log/mailman/error is:
