md5 not matching up on d-i rc2 sarge iso

[Rob Benton <rob.benton@conwaycorp.net>]

I don't know a lot about md5sums and what I've seen may not be a problem 
but I thought I would ask anyway.  I downloaded and burned the sarge iso 
with debian-installer rc2.  I used k3b for the first time in a while so 
I figured I would let it verify after I burned the iso.  It fails b/c 
the md5sums of the iso and the burned image do not match up.  Is this a 
problem?
