Today, I had an interesting "bug or a feature" in Mailman, which took me 
some time to fix.

I have a Mailman 2.1.12 which was running fine for months on a virtual host.

I did some low level kernel "experiments", and the virtual guest started 
to malfunction.

So, back to the original state - unfortunately Mailman interface didn't 
work anymore.

It exited with "Bug in Mailman version 2.1.12".

Webserver nor Mailman logs didn't give me a clue.

I browsed Mailman installation files; lists/*/config.pck suspiciously 
had a date of 1953.

Touching these files ("find | xargs touch" in the lists dir) fixed the 

Is it a bug or a feature in mailman, that when some files in "lists" 
directory are really old, Mailman refuses to work with "Bug in Mailman 
version 2.1.12"?
