[Scribus] Problem with Debian Repositories

As per the web page instructions, I've added the Scribus repositories
to my /etc/apt/sources.list file (I'm using Kubuntu 7.10 [Feisty]).

I've added the Gnupg key in apt-key, but when I run apt-get update, I'm
getting this error report:

W: GPG error: http://debian.scribus.net feisty Release: The following
signatures were invalid: BADSIG 5BC4CFB8EEF818CF Scribus Debian Archive
Signing Key <debian at scribus.info>

There is obviously a bad signature to the key.  Could the key have
become corrupted?  I've locally signed the key which generally sorts
out these problems, but I'm getting this behaviour confirmed on the
Kubuntu-users list by another Scribus user.

What is the solution to this?
