I can duplicate what I did, and it did it again:
	on master.kernel.org:
	$ cd /pub/scm/linux/kernel/git/stable/
	$ git clone -s --bare ../torvalds/linux-2.6.git/ test
	$ cat test/objects/info/alternates
	/home/ftp/pub/scm/linux/kernel/git/torvalds/linux-2.6.git/objects

I'm guessing this is because /pub/ is a symlink:
	$ ls -l /pub
	lrwxrwxrwx 1 root root 13 Feb  4  2006 /pub -> /home/ftp/pub

	$ git --version
	git version 1.5.5.3
