[packagekit] cannot subscribe to the list

[Grzegorz Dąbrowski]

I was trying to subscribe to the list
(http://lists.freedesktop.org/mailman/listinfo/packagekit) from
different email account but I get error:

Bug in Mailman version 2.1.9
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.
