A bug in git 1.6.5.2 with git log --stat: shows a negative number as a size

I'm running git version 1.6.5.2. git log --stat shows a negative diffstat size for two files that are each 2049MiB in size.

Steps to reproduce:

$ for f in 0 1 ; do dd bs=$((1024*1024)) if=/dev/zero of=$f count=2049 ; done
$ git add 0 1
$ git commit -m "test commit"
$ git log --stat
