Comment 4 for bug 328343

If the fix has been released, then it hasn't yet bubbled over to the package servers, which are still serving up version 0.3, not version 0.4. So, for example:

 cat /etc/apt/sources.list

deb http://security.ubuntu.com/ubuntu intrepid-security main restricted universe multiverse
