xfree86 Upgrade Problem

[Dave Whiteley <d.l.whiteley@ee.leeds.ac.uk>]

I have just tried an 

apt-get update; apt-get upgrade, and I am getting the following error.
.................................................................
Preconfiguring packages ...

Preparing to replace xfree86-common 4.3.0.dfsg.1-14sarge1

Is this a silly or a reportable bug?
