[Mailman-Users] We're sorry, we hit a bug! but no logs???

[Brian Parish]

Thought I had cracked it.  Click on Create to make my first list and I get:

Bug in Mailman version 2.1.5

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. 

OK fine, but there are no files in $prefix/logs and nothing in the system log.

Darkness is closing in!

Thanks for any guidance as always.

Brian
