MailMan with 3.0.4

The upgrade to 3.0.4 seems ok.

I have installed mailman with the new manuel.

But I created a list before this install, on a domain.

And lists on this domain are created, but there are 404 errors for interfaces
http://<domain>/cgi-bin/mailman/admin/<list>
http://<domain>/cgi-bin/mailman/listinfo/<domain>

ispconfig "mail warnings" shows :
Nov 18 13:38:02 ks356348 postfix/postmap[5085]: warning: /var/lib/mailman/data/virtual-mailman.db: duplicate entry: "<list>@<domain>"
(and other aliases)

/var/lib/mailman/data/aliases seems ok.
But /var/lib/mailman/data/virtual-mailman has a problem :
there are several lists of <domain> which are not deleted.

Do you know how I can correct that ?

Thanks !
